AndroidLocalization（如何將我的母語泰盧固語作爲整個應用程序語言更改）

Question

如何將我的母語泰盧固語更改爲整個應用程序語言。其實我下面嘗試了一個按鈕，泰盧固語語言顯示：

Typeface gautami_font = Typeface.createFromAsset(getAssets(), "gautami.ttf"); 
tel.setTypeface(gautami_font); 

，但是當我在首選指標TabActivity名稱顯示相同的語言將其擲錯誤。請幫幫我。提前致謝。

這是我試圖實現的完整代碼。

import android.app.TabActivity; 
import android.content.Intent; 
import android.graphics.Typeface; 
import android.os.Bundle; 
import android.widget.TabHost; 
import android.widget.TabHost.TabSpec; 
import android.widget.TextView; 

@SuppressWarnings("deprecation") 
public class ActivityStart extends TabActivity { 

TextView frst,scnd,thrd; 

TabHost tHst; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_activity_start); 
    //  frst=(TextView) findViewById(R.id.frsttxt); 
    Typeface gautami_font= Typeface.createFromAsset(getAssets(), "gautami.ttf"); 
    frst.setTypeface(gautami_font); 
    frst.setText(getString(R.string.first)); 


    tHst=getTabHost(); 
    TabSpec tSpc; 

    Intent a = new Intent(this,FrameActivity.class); 
    tSpc=tHst.newTabSpec("Ram").setIndicator(frst).setContent(a); 

    tHst.addTab(tSpc); 
    Intent b = new Intent(this,FrameActivity.class); 
    tSpc=tHst.newTabSpec("").setIndicator(getResources().getString(R.string.second)).setContent(b); 
    tHst.addTab(tSpc); 
    Intent c = new Intent(this,FrameActivity.class); 
    tSpc=tHst.newTabSpec("").setIndicator(getResources().getString(R.string.third)).setContent(c); 
    tHst.addTab(tSpc); 
} 

}

Answer 1

你得到NullPointerException行號23..so你在23行，這行是行，這些行

23獲得空值

frst.setTypeface(gautami_font); 
frst.setText(getString(R.string.first)); 

如果第一行發生異常，請嘗試查看「gautami.ttf」路徑是否正確...它是d直接複製到資產或任何子文件夾？

如果在第二行發生異常，則在行之前放置一個日誌以打印getstring值...
