MainActivity初始化
MainActivity类变量如下。
public class MainActivity extends Activity { private static MainActivity ins; protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ins = this; } public static MainActivity getInstace(){ return ins; } public void updateTheTextView(final String t) { MainActivity.this.runonUiThread(new Runnable() { public void run() { TextView textV1 = (TextView) findViewById(R.id.textV1); textV1.setText(t); } }); }}public class NotifAlarm extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { try { MainActivity .getInstace().updateTheTextView("String"); } catch (Exception e) { } }}
