Android - Adding different themes for different activity not being applied

Android - Adding different themes for different activity not being applied - java

I am new to android. I want to create a app with different theme for all the activities. I searched a lot for this but i cant find the correct solution.
Here the code

}
return super.onOptionsItemSelected(item);
}
}
Here the screen shot of output:
MainActivity Screen
Usermain Screen
the above two screens having the same theme. Please help me in this thanks in advance

I forgot to start activity with Intent. That's why the style is not applied.
have to change this
public void onClick(View v) {
setContentView(R.layout.activity_usermain);
}
with this one in MainActivity.java
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, Usermain.class);
startActivity(intent);
}
Its working good.

brother i also made an activity that wasn't much complex either just to test this issue but i didn't need to initiate any code. as u have described in the answer. It is working fine for me. All i did was change my Android Manifest file a bit and styles.xml.
after only these 2 changes i was good to go

i need to get red of the blue title bar.

You can remove the title bar forever by calling:
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
before the setContentView(R.layout.x) in your activity class.
To make the app fullscreen, you can do:
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
Again, put the above code before the setContentView method.
And make sure, if you are doing this, you should extend your Activity class by Activity and not AppCompatActivity or any other class.

Problem solved.
Because i didn't continue using the popup window,
i create a new activity instead and make the button redirect from main menu to About activity

Android Studio - Why does the ActionBar always show, even when fully disabled?

I recently started with Android application development and have come across an issue with the ActionBar. I am aware that this question has been asked a few times, and so I have made the changes necessary from what I can see from the other articles.
Currently, my main activity looks like this: image
As you can see, there is a blue bar at the top of the screen directly under the notification bar where an ActionBar is supposed to be. All of my app themes are (I believe) set to NoActionBar. I would like to get rid of this blue bar so that I can use the entire screen to put my contents.
My code is as follows:
Main_Activity.Java

import android.widget.Button;
import android.content.Intent;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button regularScorePageActivityButton = (Button)findViewById(R.id.scoreSheetButton);
regularScorePageActivityButton.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View view)
{
startActivity(new Intent(MainActivity.this, RegularScorePageActivity.class));
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;

I believe this may have something to do with a toolbar, but then again, I don't necessarily know what I'm saying :D
Any and all help is greatly appreciated. Thanks!!

Delete this from your activity_main.xml :

android:layout_width="match_parent" android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary" app:popupTheme="#style/AppTheme.PopupOverlay" />

I've tried the answer in this posts but I kept getting the same exception
com.parse.ParseRequest$ParseRequestException: invalid session token

For future reference all I had to do is uninstall the application from the emulator than run it again and the problem was solved.

You need to logout the user in Login\Signup view controllers.
Try this in viewDidLoad:

I am new to Android dev and for my project, I am creating two seekbars. The first seekbar has a minimum of 50 and a maximum of 180 while the second seekbar has a minimum of 180 and a maximum of 400. I also added textview labels below each seekbar to show the current value of each. My code compiled fine without any errors and displayed fine on the Android emulator, but when I clicked on the slider to change the value of the seekbar, my app ended up crashing and saying, "Unfortunately, your project has stopped." Below is my code:
MainActivity.java
package com.example.myname.projectname;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.SeekBar;
import android.widget.TextView;
import android.widget.SeekBar.OnSeekBarChangeListener;
import android.R.*;
public class MainActivity extends ActionBarActivity implements OnSeekBarChangeListener {
private SeekBar lowBar;
private SeekBar highBar;
private TextView lowtext;
private TextView hightext;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initializevariables();
lowBar = (SeekBar)findViewById(R.id.lowbar);
highBar = (SeekBar)findViewById(R.id.highbar);
lowtext = (TextView)findViewById(R.id.lowval);
hightext = (TextView)findViewById(R.id.highval);
lowBar.setOnSeekBarChangeListener(this);
highBar.setOnSeekBarChangeListener(this);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
private void initializevariables(){
lowBar = (SeekBar) findViewById(R.id.lowbar);
highBar = (SeekBar) findViewById(R.id.highbar);
}
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser)
{
progress = 0;
int lowbarmin = progress + 50;
int highbarmin = progress + 180;
lowtext.setText(lowbarmin);
hightext.setText(highbarmin);
}

Thank you in advance!

Your seekbar's minimum value is 50, you can not increase +50;
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser)
{
int lowbarmin = progress + 1;
int highbarmin = progress + 1;
lowtext.setText(lowbarmin);
hightext.setText(highbarmin);
}

Crash is probably because of these lines :
lowtext.setText(lowbarmin);
hightext.setText(highbarmin);
When you do this and the value of lowbarmin and highbarmin are integers, android looks for string resources with those values as their resourceId and it cannot find one.
So what you instead want to do is, pass string values to setText() :
lowtext.setText(Integer.toString(lowbarmin));
hightext.setText(Integer.toString(highbarmin));

Android: Application is crashing On Startup

I am a novice and I'm just creating a simple Android app in which there are 2 buttons that take you to different pages when clicked, which have different functions.
However, my app crashes on start-up, simply saying
Unfortunately [app name] has stopped
and I don't understand
As I have barely made any changes to my MainActivity.java, the code seems to be well written, and eclipse displays no errors... Any help, please? I have searched around Stack, but I can't find anything specific to this...
Here is my MainActivity.java:
package com.example.helper;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
/**Called upon when the user clicks the 'Abbreviations' button*/
public void listDefinitions (View view){
Intent intent = new Intent(this, ListDefinitions.class);
startActivity(intent);
}
/**Called upon when the user clicks the 'Assistant' button*/
public void openAssistant (View view){
Intent intent = new Intent(this, Assistant.class);
startActivity(intent);
}
}
Here is my activity_main.xml:

</RelativeLayout>
My ListDefinitions.java & Assistant.java are untouched at this point.
My Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.theocratichelper"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="19"
android:targetSdkVersion="21" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".ListDefinitions"
android:label="#string/title_activity_list_definitions"
android:parentActivityName=".MainActivity" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.theocratichelper.MainActivity" />
</activity>
<activity
android:name=".PreachAssistant"
android:label="#string/title_activity_preach_assistant"
android:parentActivityName=".MainActivity" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.theocratichelper.MainActivity" />
</activity>
</application>
</manifest>

It's your manifest, replace the "last" activity in your manifest by this :
<activity
android:name=".Assistant"
android:label="#string/title_activity_preach_assistant"
android:parentActivityName=".MainActivity" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.theocratichelper.MainActivity" />
</activity>
Your class name is Assistant and not PreachAssistant i presume.

Just replace the last activity in Android Manifest by this.
<activity
android:name=".Assistant"
android:label="#string/title_activity_preach_assistant"
</activity>
