Android Handler Thread HandlerThread

Android Handler Thread HandlerThread

從主線程發送消息到子線程。
子線程必須創建Looper，
handlerThread.getLooper()，
Looper.prepare()，Looper.loop()

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = findViewById(R.id.button2);

Tthread tthread = new Tthread();
tthread.start();
T3();
T4();

button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
hh.sendEmptyMessage(12);
handler.sendEmptyMessage(12);
handlerT4.sendEmptyMessage(12);
}
});
}

protected void T3() {
HandlerThread handlerThread = new HandlerThread("name-thread");
handlerThread.start();
handler = new Handler(handlerThread.getLooper()) {
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
System.out.println(Thread.currentThread().getName());
System.out.println("T33333333333333333");
}
};
}

protected void T4() {
Thread thread = new Thread() {
@Override
public void run() {
super.run();
Looper.prepare();
handlerT4 = new Handler() {
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
System.out.println("T44444444444444444444");
}
};
Looper.loop();
}
};
thread.start();
}

class Tthread extends Thread {
@Override
public void run() {
super.run();
Looper.prepare();
hh = new HH();
Looper.loop();
}
}

class HH extends Handler {
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
System.out.println("HHHHHHHHHHHHHHHHHHHHHHHH");
System.out.println(Thread.currentThread().getName());
}
}

為Fragment添加一個接口，是能在MainActivity下找到Fragment下的子控件View

public class F1 extends Fragment {

private View view;

public Find_button find_button;

public void getFind_button(Find_button find_button) {

this.find_button = find_button;

}

@Override

public void onCreate(@Nullable Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

}

@Nullable

@Override

public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {

super.onCreateView(inflater, container, savedInstanceState);

view = inflater.inflate(R.layout.f1, null);

return view;

}

@Override

public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {

super.onViewCreated(view, savedInstanceState);

find_button.button(view);

}

interface Find_button {

void button(View view);

}

-----------------------------------

public class MainActivity extends AppCompatActivity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

addf1();

}

protected void addf1() {

FragmentManager fragmentManager = getFragmentManager();

FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();

F1 f1 = new F1();

fragmentTransaction.add(R.id.f1, f1, "f1");

fragmentTransaction.commit();

f1.getFind_button(new Find_button() {

@Override

public void button(View view) {

final Button button = view.findViewById(R.id.button);

button.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

button.setText("F1.Button");

Toast.makeText(MainActivity.this, "F1.Button", Toast.LENGTH_SHORT).show();

}
