Okay guys. I'm doing a project and I have put a button in the action bar which translates from Bulgarian to English and vice verse. I have make the change in locale but my problem is that after I click the button the language across the app changes but the text on the button in the action bar does not. I have made two folders values-bg and values-en and the string I'm taking for the button is declared in both string.xmls but the text does not change at all.
This is the code :
import java.util.Locale;
import com.pushbots.push.Pushbots;
import android.net.Uri;
import android.os.Bundle;
import android.app.ActionBar;
import android.app.Activity;
import android.content.Intent;
import android.content.res.Configuration;
import android.graphics.Color;
import android.graphics.drawable.ColorDrawable;
import android.util.Log;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends Activity implements OnClickListener {
Button lBtn, sBtn, cBtn, aBtn;
TextView hLink;
private String loc = "loc";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ActionBar bar = getActionBar();
bar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#118cec")));
setContentView(R.layout.activity_main);
this.lBtn = (Button) findViewById(R.id.button1);
lBtn.setOnClickListener(this);
this.sBtn = (Button) findViewById(R.id.button2);
sBtn.setOnClickListener(this);
this.cBtn = (Button) findViewById(R.id.button3);
cBtn.setOnClickListener(this);
this.aBtn = (Button) findViewById(R.id.button4);
aBtn.setOnClickListener(this);
this.hLink = (TextView) findViewById(R.id.hlink);
hLink.setOnClickListener(this);
}
@Override
public void onClick(View v) {
if (v.getId() == lBtn.getId()) {
startActivity(new Intent(this, lect_list.class));
Log.d(loc, "pressed");
} else if (v.getId() == sBtn.getId()) {
Toast t = Toast.makeText(this, "Text",
Toast.LENGTH_LONG);
t.show();
} else if (v.getId() == cBtn.getId()) {
Toast t = Toast.makeText(this,
"Text",
Toast.LENGTH_LONG);
t.show();
} else if (v.getId() == aBtn.getId()) {
startActivity(new Intent(this, dlect.class));
Log.d(loc, "pressed");
}
else if (v.getId() == hLink.getId()) {
Toast t = Toast.makeText(this, "Text",
Toast.LENGTH_LONG);
t.show();
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
}
}
@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) {
// TODO Auto-generated method stub
if (item.getItemId() == R.id.trans) {
Toast t = Toast.makeText(this, "Translation", Toast.LENGTH_LONG);
t.show();
Locale mLocale = new Locale("bg");
Locale.setDefault(mLocale);
Configuration config = getBaseContext().getResources()
.getConfiguration();
if (!config.locale.equals(mLocale)) {
config.locale = mLocale;
getBaseContext().getResources().updateConfiguration(config,
null);
setContentView(R.layout.activity_main);
this.lBtn = (Button) findViewById(R.id.button1);
lBtn.setOnClickListener(this);
this.sBtn = (Button) findViewById(R.id.button2);
sBtn.setOnClickListener(this);
this.cBtn = (Button) findViewById(R.id.button3);
cBtn.setOnClickListener(this);
this.aBtn = (Button) findViewById(R.id.button4);
aBtn.setOnClickListener(this);
} else {
mLocale = new Locale("en");
config.locale = mLocale;
getBaseContext().getResources().updateConfiguration(config,
null);
setContentView(R.layout.activity_main);
this.lBtn = (Button) findViewById(R.id.button1);
lBtn.setOnClickListener(this);
this.sBtn = (Button) findViewById(R.id.button2);
sBtn.setOnClickListener(this);
this.cBtn = (Button) findViewById(R.id.button3);
cBtn.setOnClickListener(this);
this.aBtn = (Button) findViewById(R.id.button4);
aBtn.setOnClickListener(this);
}
}
return super.onOptionsItemSelected(item);
}
}
Is it possible somehow to inflate the menu one more time. After i change the locale i set the new activity but not the new menu. Can i call getMenuInflater().inflate(R.menu.main, menu); somehow in my If block ?
Call invalidateOptionsMenu() after you change locale… or simply restart your app :)
