android 音声の周波数を作成

android 音声の周波数を作成

byte b = (byte)(Math.sin(bufferIndex/2*Math.PI(SamplingRate /Frequency))

角度 =bufferIndex /2*Math.PI(4400/800);

【Android】快速切换到主线程更新UI的几种方法

【Android】快速切换到主线程更新UI的几种方法
方法一： view.post(Runnable action)
textView.post(new Runnable() {
@Override
public void run() {
textView.setText("更新textView");
//还可以更新其他的控件
imageView.setBackgroundResource(R.drawable.update);
}
});

方法二： activity.runOnUiThread(Runnable action)
public void updateUI(final Context context) {
((MainActivity) context).runOnUiThread(new Runnable() {
@Override
public void run() {
//此时已在主线程中，可以更新UI了
}
});
}

方法三： Handler机制
...

Android Handler Thread HandlerThread

Android Handler Thread HandlerThread

Handler.Callback callback = new Handler.Callback()

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

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()
