私のアプリケーションでは、GPSをアクティブにするために電話の設定解除アクティビティに移動し、次のコードコードを使用してアプリケーションに戻る必要があります。
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivityForResult(intent);
しかし、それを使用したとき、私は自分のアプリに戻ることができませんでした。私が押し返したとき、私はこれを試しました:
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivityForResult(intent, 0);
次に、このコードですべてのタイプの結果を呼び出しました
public void onActivityResult(int requestCode, int resultCode, Intent x){
if(requestCode == 0){
if(resultCode == RESULT_CANCELED){
Button b = (Button)findViewById(R.id.button1);
b.setText("ON");
b.setTextColor(0xff2d9ede);
Intent k = new Intent(getApplicationContext(), serve.class);
startService(k);
}
}
if(resultCode == RESULT_FIRST_USER){
Button b = (Button)findViewById(R.id.button1);
b.setText("ON");
b.setTextColor(0xff2d9ede);
Intent k = new Intent(getApplicationContext(), serve.class);
startService(k);
}
if(resultCode == RESULT_OK){
Button b = (Button)findViewById(R.id.button1);
b.setText("ON");
b.setTextColor(0xff2d9ede);
Intent k = new Intent(getApplicationContext(), serve.class);
startService(k);
}
}
}
しかし、これも機能しませんでした..同じことが起こりました(私のアプリに戻らなかった)..アイデア?? ... 前もって感謝します
