Not sure if EditText or KeyEvent are not listening or is an XML problem

I'm trying to make a game but I need the user to fill in the username before jumping from Main Activity to Activity 2.
If the username is empty, itdoesn't do anything.
If the username has at least one letter, it launches second activity.
In my case it never works and I don't know what I'm doing wrong.
This is my code.
MainActivity.java
public class MainActivity extends AppCompatActivity {
EditText et1;
TextView tv1;
String usuario;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
et1 = findViewById(R.id.et1);
tv1 = findViewById(R.id.tv1);
/*Button next = findViewById(R.id.boton);
next.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent myIntent = new Intent(view.getContext(), MainActivity2.class);
startActivity(myIntent);
}
});*/
et1.setOnKeyListener(new View.OnKeyListener() {
#Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
usuario = et1.getText().toString();
if(et1.getText().toString().trim().length() > 0) {
if((event.getAction() == KeyEvent.ACTION_DOWN) && (event.getAction() == KeyEvent.KEYCODE_ENTER)) {
startActivity2();
}
}
return false;
}
});
}
public boolean startActivity2(){
Intent myIntent = new Intent(this, MainActivity2.class);
startActivity(myIntent);
return false;
}
And the activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<TextView
android:id="#+id/tv1"

android:inputType="text"
android:maxLines="1"
android:maxLength="11"
android:layout_toRightOf="#+id/tv1"
android:layout_centerInParent="true"/>
</RelativeLayout>
I tried for the ifs !isEmpty(), trim(), !equals and absolutely nothing.
Here is the manifest, if necesarry.
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.juegocartas3">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/Theme.JuegoCartas3">
<activity
android:name=".MainActivity3"
android:exported="false" />
<activity

android:exported="false" />
<activity

android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

Try this-
public class MainActivity extends AppCompatActivity {
EditText et1;
TextView tv1;
String usuario;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
et1 = findViewById(R.id.et1);
tv1 = findViewById(R.id.tv1);
et1.setOnEditorActionListener(new TextView.OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if ((actionId & EditorInfo.IME_MASK_ACTION) == EditorInfo.IME_ACTION_DONE) {
usuario = et1.getText().toString();
if (usuario.trim().length() > 0) {
startActivity2();
} else {
Toast.makeText(getApplicationContext(), " Please add User name", Toast.LENGTH_LONG).show();
}
return true;
}
return false;
}
});
public void startActivity2() {
Intent myIntent = new Intent(this, MainActivity2.class);
startActivity(myIntent);
}}

Open specific links in browser, instead of webview by regex

I'm using parts of code form some tutorial to create webview app. Goals is - to open links, that not contain appdev365 in browser, not in webview. I am completly noob at android development, so all that i've searched - didn't match to my(from tutorial) code.
MainActivity.java
package com.example.ynt;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.content.Intent;
public class MainActivity extends AppCompatActivity {
private WebView webView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = (WebView) findViewById(R.id.webview);
webView.setWebViewClient(new WebViewClient());
webView.loadUrl("https://yatln.com/appdev365/index.php");
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
}
#Override
public void onBackPressed() {
if (webView.canGoBack()) {
webView.goBack();
} else {
super.onBackPressed();
}
}
}

SOLUTION (by Varma Lanke):
https://gist.github.com/codedamage/8f98e2ed13d1d1fa05e5d43e67ea3e6c
private WebView htmlWebView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
htmlWebView = (WebView)findViewById(R.id.webview);
htmlWebView.setWebViewClient(new CustomWebViewClient());
WebSettings webSetting = htmlWebView.getSettings();
webSetting.setJavaScriptEnabled(true);
webSetting.setDisplayZoomControls(true);
htmlWebView.loadUrl("https://yatln.com/appdev365/index.php");
}
private class CustomWebViewClient extends WebViewClient{
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(url.contains("appdev365"))
view.loadUrl(url);
else{
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(i);
}
// view.loadUrl(url);
return true;
}
}

For you should use shouldOverrideUrlLoading method, once try the below one
private WebView htmlWebView;
String url = "https://yatln.com/appdev365/index.php";
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mainpage);
htmlWebView = (WebView)findViewById(R.id.webView);
if(url.contains("appdev365"))
htmlWebView.setWebViewClient(new CustomWebViewClient());
WebSettings webSetting = htmlWebView.getSettings();
webSetting.setJavaScriptEnabled(true);
webSetting.setDisplayZoomControls(true);
htmlWebView.loadUrl(url);
}
private class CustomWebViewClient extends WebViewClient{
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(url.equalsIgnoreCase("appdev365"))
view.loadUrl(url);
return true;
}
}

This code opens browser and specified link (ex. google.com):
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));
startActivity(browserIntent);

Button displays toast and starts service

I have two buttons (start/stop) that when clicked need to have a Toast pop up saying what has happened to the Service. Start = popup of "service has started" and the service actually starts. The service isn't finished and will be grabbing some GPS info later on.
Anyway, none of my Toasts show up and I'm hoping I'm not missing something obvious.
Main (Activity)
public class Main extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button startBtn = (Button) findViewById(R.id.startButton);
startBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
startService(new Intent(getBaseContext(), ParseService.class));
}
});
Button stopBtn = (Button) findViewById(R.id.startButton);
stopBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
stopService(new Intent(getBaseContext(), ParseService.class));
}
});
}
}
ParseService
public class ParseService extends Service {
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public int onStartCommand(Intent e, int flags, int startId){
Toast.makeText(this, "Service has Started", Toast.LENGTH_LONG).show();
return START_STICKY;
}
#Override
public void onDestroy(){
super.onDestroy();
Toast.makeText(this, "Service has Stopped", Toast.LENGTH_LONG).show();
}
}
activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textAlignment="center"
tools:context="${packageName}.${activityClass}" >
<Button
android:id="#+id/startButton"
android:layout_width="150dp"
android:layout_height="60dp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="92dp"
android:text="Start" />
<Button
android:id="#+id/stopButton"
android:layout_width="150dp"
android:layout_height="60dp"
android:layout_alignLeft="#+id/startButton"
android:layout_below="#+id/startButton"
android:layout_marginTop="74dp"
android:text="Stop" />
</RelativeLayout>

You are supposed to use the Application's Context from a Service and not the Service's Context.
From your Service:
Toast.makeText(getApplicationContext(), // application Context not 'this'
"Service has Started",
Toast.LENGTH_LONG).show();
Alternatively, you could display them from your Activity before you invoke the Service if you wish but I think where you have the calls currently positioned makes more sense and would reduce repetition later on as long as you always want the Toast displayed.
EDIT:
Ok, after making a quick test app I think I found what might be going wrong for you.
Do you have the Service declared in your AndroidManifest.xml??
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.indivisible.testapp">
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme">
<activity
android:name=".toasts.ToastActivity"
android:label="#string/title_activity_toast">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<!-- Define your Service as below.
In my case the path is:
.../TestApp/app/src/main/java/com/indivisible/testapp/toasts/ToastService.java
Android Studio has a nice auto-complete when you press '.'
-->
<service
android:name=".toasts.ToastService"
android:label="ToastService">
</service>
</application>
</manifest>

It seems like your service is not getting started, make sure the service is declared in the manifest and enabled as below:
<service
android:name=".ParseService"
android:enabled="true" />
Hope this helps

Music don't start on button click

When I go to install the app on the device, I click the button but nothing happen.
I want to make device play tosse.acc from res/raw when I click the button...
Ok resolved the problem :) thanks for answers guys :D ( i have changed the name of the song from tosse to toxxe)
public void tosse1(View v) {
Button one = (Button)this.findViewById(R.id.button1);
final MediaPlayer mp = MediaPlayer.create(this, R.raw.toxxe);
one.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Resume the music player
mp.start();
}
});
}
Here my code:
public void tosse1(View v) {
Button one = (Button)this.findViewById(R.id.button1);
final MediaPlayer mp = new MediaPlayer();
mp.create(this, R.raw.tosse);
one.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Resume the music player
mp.start();
}
});
}
activity_main:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

Declare your mp as private variable in your class:
public class PlayaudioActivity extends Activity {
private MediaPlayer mp;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button b = (Button) findViewById(R.id.button1);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
stopPlaying();
mp = MediaPlayer.create(PlayaudioActivity.this, R.raw.tosse);
mp.start();
}
});
}
private void stopPlaying() {
if (mp != null) {
mp.stop();
mp.release();
mp = null;
}
}
}

Try getting a Mediaplayer Instance like this:
final MediaPlayer mp = MediaPlayer.create(this, R.raw.tosse);
should solve your problem, because it also prepares the MediaPlayer, see documentation:
public static MediaPlayer create (Context context, int resid) Added in API level 1
Convenience method to create a MediaPlayer for a given
resource id. On success, prepare() will already have been called and
must not be called again.
When done with the MediaPlayer, you should call release(), to free the
resources. If not released, too many MediaPlayer instances will result
in an exception.

Please write below code instead of your code for add multiple activities in one TabActivity, it will solve your problem.

Create an intermediate activity as below by extending TabActivitygroup
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
public class InterMediateActivity extends TabActivityGroup{
String TabID;
String TabName;
#Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
TabID=getIntent().getStringExtra("TabID");
TabName=getIntent().getStringExtra("TabName");
Log.i("Tab from intermediate",""+TabID+" "+TabName);
filterTabs(TabID);
}
private void filterTabs(String TabID)
{
if(TabID.trim().equals("Home"))
{
startChildActivity("Options", new Intent(this,HomePage.class));
//TabsUtil.setTabIndicator(specTab,"Wall", null, tabView);
}
if(TabID.trim().equals("Menu"))
{
startChildActivity("Options", new Intent(this,MenuPage.class));
//TabsUtil.setTabIndicator(specTab,"Wall", null, tabView);
}
if(TabID.trim().equals("Gallery"))
{
Log.i("GALLERY check", "gallery check");
startChildActivity("Options", new Intent(this,GalleryPage.class));
}
if(TabID.trim().equals("Aboutus"))
{
startChildActivity("Options", new Intent(this,AboutUsPage.class));
}
if(TabID.trim().equals("Location"))
{
startChildActivity("Options", new Intent(this,LocationList.class));
}
if(TabID.trim().equals("Events"))
{
startChildActivity("Options", new Intent(this,EventsPage.class));
}
if(TabID.trim().equals("TipCalculator"))
{
startChildActivity("Options", new Intent(this,TipCalculatorPage.class));
}
if(TabID.trim().equals("Special"))
{
startChildActivity("Options", new Intent(this,SpecialPage.class));
}
if(TabID.trim().equals("NowRunning"))
{
startChildActivity("Options", new Intent(this,NowRunningPage.class));
}
if(TabID.trim().equals("ShowTimes"))
{
startChildActivity("Options", new Intent(this,ShowTimePage.class));
}
if(TabID.trim().equals("GpsCoupon"))
{
startChildActivity("Options", new Intent(this,GPSCouponPage.class));
}
if(TabID.trim().equals("UpcomingMovieNames"))
{
startChildActivity("Options", new Intent(this,UpcomingPage.class));
}
if(TabID.trim().equals("PriceListOfServices"))
{
startChildActivity("Options", new Intent(this,ServicesPage.class));
}
if(TabID.trim().trim().equals("NewsLetter"))
{
Log.i("newsletter check", "newsletter check");
startChildActivity("Options", new Intent(this,NewsLetter.class));
}
if(TabID.trim().trim().equals("Website"))
{
startChildActivity("Options", new Intent(this,WebSitePage.class));
}
}
}
And instead of setting the tabs from tabactivity directly you can set them inside the intermediate activity. Then call the Intermediate activity from the tabactivity.
Intent intent = new Intent(this, InterMediateActivity.class);
intent.putExtra("TabID", item.elementAt(0));
intent.putExtra("TabName", item.elementAt(1));
