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:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/texto"
android:layout_centerVertical="true"
android:layout_marginRight="50dp"
android:layout_marginLeft="50dp"
android:background="#ff8200"
android:layout_marginEnd="50dp"
android:layout_marginStart="50dp" />
<Button
android:id="#+id/boton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="jump"
android:layout_below="#+id/tv1"/>
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/et1"
android:ems="7"
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:name=".MainActivity2"
android:exported="false" />
<activity
android:name=".MainActivity"
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);
}}

Run Time Main Activity not come after Splash Activity and app close

Everything in my code looks good in both the .java and .xml files (according to the software) because I have no errors yet every time I click the app icon in the emulator, it brings up the splash screen then the app exits without showing my main activity. Here's my code so far:
SplashActivity.java
public class SplashActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//hide title bar of activity
getWindow().requestFeature(Window.FEATURE_NO_TITLE);
//Making activity full screen
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_splash);
int t =3000; //time for spash screen 3000 means 3sec
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
startActivity(new Intent(SplashActivity.this, MainActivity.class));
}
},t);
}
}
SplashActivity.xml
<ImageView
android:layout_width="250dp"
android:layout_height="250dp"
android:src="#drawable/icon"
android:text="Hello World!"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
MainActivity.java:
public class MainActivity extends AppCompatActivity
{
String webAdress ="https://www.google.com/";
WebView webView;
FrameLayout frameLayout;
ProgressBar progressBar;
#Override

super.onCreate(savedInstanceState);

webView.setWebViewClient(new HelpClient());
webView.setWebChromeClient(new WebChromeClient() {

frameLayout.setVisibility(View.VISIBLE);
progressBar.setProgress(newProgress);

if (newProgress == 100) {
frameLayout.setVisibility(View.GONE); // Hide progress bar when page is loaded

}
super.onProgressChanged(view, newProgress);
}
});
webView.getSettings().setJavaScriptEnabled(true); //enable javaScript
//check internet connection
if (haveNetworkConnection()) {
webView.loadUrl(webAdress);
} else {
Toast.makeText(this, "No internet Connection", Toast.LENGTH_SHORT).show();
}

return true;
}
//if it was the back or there is no web page history, bubble up to the default system behaviour
return super.onKeyDown(keyCode, event);
}
}

Any hints would be greatly appreciated, thank you!

The problem is in onCreate method of MainActivity, you do not provide any UI (xml layout file), as a result, the app cannot find view elements to init, set listeners, etc. I guess you can find an exception in logcat when your app close.
Solution: Provide a layout xml file for MainActivity
public class MainActivity extends AppCompatActivity {
String webAdress ="https://www.google.com/";
WebView webView;
FrameLayout frameLayout;
ProgressBar progressBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main); // Add this line
webView = (WebView) findViewById(R.id.webView);
...
}
}

try use
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
finish();

Your code is not so good. If you want to show splashscreen only when app start I recommend using the following code:
AndroidManifest.xml
<activity android:name=".view_layer.activities.SplashScreenActivity"
android:theme="#style/SplashTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
styles.xml
<style name="SplashTheme" parent="#android:style/Theme.NoTitleBar.Fullscreen">
<item name="android:windowBackground">#drawable/splash</item>
</style>
SplashscreenActivity.java
public class SplashscreenActivity extends AppCompatActivity {
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
startActivity(new Intent(this, MainActivity.class));
finish();
}
}

</application>
</manifest>

you have to do below things to achieve what you want
whenever you open activity you have to save previous activity name in prefrance.
when you press resume button get activity name from prefrance and open activity using below code
Intent intent = new Intent();
intent.setClassName("com.android.browser","com.android.BrowserActivity");
context.startActivity(intent);
// clear previous activity before start
when you app relaunch app then do step 2 again in main Activity
in this type of approch you have to maintain flow of application using singletone or clear stack before launch activity. because you have to handle backbutton

Using QR and NFC technology together in an Android app

I am developing an Android app consisting of two activites so far. The first activity (MainActivity) is started when the app is launched or when a QR code is scanned. The MainActivity starts the second activity (NFCActivity) when the user presses a button. The NFCActivity waits for the user to tap a NFC token, reads out data from the token, and returns the read data to the MainActivity.
This works fine if the app is started manually. If the app is started by scanning a QR code, taping the NFC tag does not invoke the NFCActivity's onNewIntent() method as exepcted, but instead creates a new instance of the NFCActivity on top of the already displayed one.
The enableForegroundDispatch() method is called and FLAG_ACTIVITY_SINGLE_TOP should be set. Relevant source code of a minimal example is provided below. Any help would be highly appreciated!
MainActivity:
public class MainActivity extends Activity {
private EditText dataRead;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_start);
dataRead = (EditText) findViewById(R.id.data);
final Button readKeyButton = (Button) findViewById(R.id.readNFC);
readKeyButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent keyIntent = new Intent(MainActivity.this,
NFCActivity.class);
keyIntent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
startActivityForResult(keyIntent, 1);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode,
Intent intent) {
if (requestCode == 1) {
String result = intent.getExtras().getString("resultData");
this.dataRead.setText(result);
}
}
}

In case somebody is facing a similar problem: I was finally able to overcome the issue described above by setting the android:launchMode property for the MainActivity to singleInstance.

Android Splash Screen

this is what i have in my package explorer so lets start from the top

public class MainActivity extends Activity {
#Override

// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;

Change your <application> tag to the following. You didn't have SplashActivity declared, and had your MainActivity setup as the launcher Activity.
<application
android:allowBackup="true"

The Best way implement a splash screen, to be displayed every time your application is launched will be to create a new activity.
public class SplashScreen extends Activity {
private Handler mHandler;
private Runnable myRunnable;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Just create simple XML layout with i.e a single ImageView or a custom layout
setContentView(R.layout.splash_screen_layout);
mHandler = new Handler();
myRunnable = new Runnable() {
#Override
public void run() {
Intent intent = new Intent(SplashScreen.this, MainActivity.class);
startActivity(intent);
finish();
}
};
}
#Override
public void onBackPressed() {
// Remove callback on back press
if (mHandler != null && myRunnable != null) {
mHandler.removeCallbacks(myRunnable);
}
super.onBackPressed();
}
#Override
protected void onPause() {
// Remove callback on pause
if (mHandler != null && myRunnable != null) {
mHandler.removeCallbacks(myRunnable);
}
super.onPause();
}
#Override
protected void onResume() {
// Attach and start callback with delay on resume
if (mHandler != null && myRunnable != null) {
mHandler.postDelayed(myRunnable, ConstantValues.SPLASH_TIME_OUT);
}
super.onResume();
}
}

You can easily access splash screen like this. such as
public class MainActivity extends Activity {
private ImageView splashImageView;
private boolean splashloading = false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
splashImageView = new ImageView(this);
splashImageView.setScaleType(ScaleType.FIT_XY);
splashImageView.setImageResource(R.drawable.ic_launcher);
setContentView(splashImageView);
splashloading = true;
Handler h = new Handler();
h.postDelayed(new Runnable() {
public void run() {
splashloading = false;
// set your layout file in below
setContentView(R.layout.activity_main);
}
}, 3000);
}
}
it will be works 100%.

Here is a simple one!
