I had an application which have option to choose language at start. Currently when the application start i had to click on choose language and then pop up appears containing different languages. But I don't want to click on choose language option for displaying pop up. I want my app to automatically appears a pop up to choose language on app start. I followed this tutorial. Here is the snapshot of the thing I would like to achieve.
Here is a code of Mainactivity.java
public class AndroidLocalize extends Activity {
Spinner spinnerctrl;
Button btn;
Locale myLocale;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
spinnerctrl = (Spinner) findViewById(R.id.spinner1);
spinnerctrl.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
if (pos == 1) {
Toast.makeText(parent.getContext(), "You have selected Tamil", Toast.LENGTH_SHORT).show();
setLocale("ta");
} else if (pos == 2) {
Toast.makeText(parent.getContext(), "You have selected Hindi", Toast.LENGTH_SHORT).show();
setLocale("hi");
} else if (pos == 3) {
Toast.makeText(parent.getContext(), "You have selected English", Toast.LENGTH_SHORT).show();
setLocale("en");
}
else if (pos == 4) {
Toast.makeText(parent.getContext(), "You have selected Arabic", Toast.LENGTH_SHORT).show();
setLocale("ar");
}
}
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
}
public void setLocale(String lang) {
myLocale = new Locale(lang);
Resources res = getResources();
DisplayMetrics dm = res.getDisplayMetrics();
Configuration conf = res.getConfiguration();
conf.locale = myLocale;
res.updateConfiguration(conf, dm);
Intent refresh = new Intent(this, AndroidLocalize.class);
startActivity(refresh);
}
}
My main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="@+id/greet"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/greet"
android:textSize="25sp" android:gravity="center" android:paddingTop="25sp" />
<ImageView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:src="@drawable/sachin" android:paddingTop="25sp" />
<TextView
android:textColor="#ffffff"
android:id="@+id/textView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/langselection"
android:textAppearance="?android:attr/textAppearanceMedium" android:gravity="center" android:paddingTop="25sp"/>
<Spinner
android:popupBackground="#ff004372"
android:id="@+id/spinner1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:entries="@array/languages"
android:gravity="center"
android:paddingTop="25sp" />
</LinearLayout>
Try this in onCreate()
of your Activity
:
spinnerctrl = (Spinner) findViewById(R.id.spinner1);
findViewById(android.R.id.content).post(new Runnable() {
@Override
public void run() {
spinnerctrl.performClick();
}
});
//Rest of the code...
It will automatically open the spinner
popup during onCreate of Activity
Update
To cancel the runnable use:
Declare:
Handler handler;
Runnable runnable;
inside onCreate()
handler = new Handler();
runnable = new Runnable() {
public void run() {
spinnerctrl.performClick();
}
};
handler.postDelayed(this, 500);
Now cancel it in onItemSelected
using:
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
if (pos == 1) {
Toast.makeText(parent.getContext(), "You have selected Tamil", Toast.LENGTH_SHORT).show();
setLocale("ta");
handler.removeCallbacks(runnable);
}
//rest of the condition
