区分Handler和HandlerThread
Handler实例可以在主线程创建,也可以在子线程创建。
在子线程中创建时通过Looper,以下示例:
public class MainActivity extends AppCompatActivity {
HandlerThread handlerThread;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
handlerThread = new HandlerThread("子线程");
handlerThread.start();
Looper looper = handlerThread.getLooper();
final Handler handler = new Handler(looper) {
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
Log.d("----->", "线程:" + Thread.currentThread().getName());
}
};
findViewById(R.id.bt).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
handler.sendEmptyMessage(100);
}
});
}
@Override
protected void onDestroy() {
super.onDestroy();
handlerThread.quit();
}
}
