I want to create an email link in an Android app.
If I do it this way:
<TextView
android:text="xxxx#yyyy.zz"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingTop="10dp"
android:autoLink="email"/>
Then it works as it should.
I do, however, want to do it in code. The following example is a new Android project in Android Studio with a basic activity. I have added the marked code and added the id "mytest" to the auto-generated layout.
package com.example.bjursus.myapplication;
import android.content.Intent;
import android.os.Bundle;
import android.support.constraint.ConstraintLayout;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.text.util.Linkify;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;
import android.view.ViewGroup;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
// Added code - start
getIntent().setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
ConstraintLayout clo = (ConstraintLayout) findViewById(R.id.mytest);
TextView tv = new TextView(getApplicationContext());
tv.setText("zxxx#yyyy.zz");
Linkify.addLinks(tv, Linkify.EMAIL_ADDRESSES);
tv.setLinksClickable(true);
clo.addView(tv);
// Added code - end
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
}
#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);
}
}
This will give me the email link, but when I click it I get this exception:
AndroidRuntimeException: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?
Any suggestions?
Simply add this to the code
getIntent().setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
This will tell your activity it is okay to start a new task.

I recently updated with Support Library 24.2.1 and I rebuild my App with it..
But the App crashed on Startup..
Logcat shows error like -
No resource found for abc_test_vector.xml
I've searched in AppCompat 24.2.1 & found the file in res/drawable/ then why this error?
Even the Sample App didn't work -

Here is my menu xml item
<item
android:id="#+id/menu_search"
android:title="#string/menu_search"
appcompat:actionViewClass="android.support.v7.widget.SearchView"
appcompat:showAsAction="always"/>
For Lollipop and above versions place the below code in onCreateOptionsMenu() before return statement
SearchView searchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(R.id.action_search));
ImageView searchButton = (ImageView) searchView.findViewById(android.support.v7.appcompat.R.id.search_button);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
searchButton.setImageTintList(ColorStateList.valueOf(getResources().getColor(R.color.yourDesiredColor)));
}
might be useful for someone.
Add This as Your Menu Item
android:icon="#drawable/search"
I'm trying to create an animation for an ImageView which shows like picture below (collected on Stackoverflow).
I want to do this because I want it shows when my location is locating. I've tried to find keywords but i couldn't found anything. Thanks.
You can use Wavedrawable Library.
it is available in GitHub with sample projects.

waveDrawable = new WaveDrawable(Color.parseColor("#8e44ad"), 500);
imageView.setBackgroundDrawable(waveDrawable);
interpolator = new LinearInterpolator();
waveDrawable.setWaveInterpolator(interpolator);
waveDrawable.startAnimation();

Replace your code with the following code:

I have 2 activities. One is the main activity. One is the Preference activity. I'm trying to change the background color of the activity based on the color selected in a RadioGroup in the Preference activity.
This is the class file for the main activity.

#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_mod_list);
savedData=getSharedPreferences("MyPrefs",0);
String colorMine=savedData.getString("color", "deflt");
TextView head=(TextView) findViewById(R.id.mymodlist);
head.setText(colorMine);
ArrayAdapter<String> moduleAdapter = new ArrayAdapter<String>(this, R.layout.activity_list_view, R.id.list1, moduleArray);
final ListView list = (ListView) findViewById(R.id.mod_list);
list.setAdapter(moduleAdapter);
}
});
}

This is the class file for the Preference class.

SharedPreferences.Editor editor=savedData.edit();

}
}
}
I haven't actually done the background color part. I'm just trying to display the value in a TextView currently. But it shows only the default value all the time. What I'm trying to do is.
Click on Settings.
Click on RadioButton for color desired.
Click on Save button.
Click on back key to return to main activity.
I'm pretty new to this and might be doing something wrong. But I just can't figure out what it is.
savedData=getSharedPreferences("MyPrefs",0);
it's diferent from
savedData=getSharedPreferences("MyPref", 0);
Use the same file when you open your SharedPreferences
