Android Studio 代码中的 2 个活动问题
2 Activities Problem in Android Studio Code
我正在通过 Android Studio 编写一个小应用程序。我正在从事 2 项活动。我的第一个 activity 打开第二个后，我的应用程序停止响应（当我通过模拟器 运行 应用程序时）。我意识到问题首先出现是因为我在第二个 activity 中插入了 for 循环。但是笔记的音频输出还是在后台完成的
如果你能在这里帮助我，那就太好了。
这里是代码：
public class MainActivity extends AppCompatActivity {
private Button myButton1, myButton2;
private EditText number;
TextView display;
int time = 0;
Bundle b;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
number = (EditText) findViewById(R.id.editTextNumber);
myButton2 = (Button) findViewById(R.id.button);
display = (TextView) findViewById(R.id.textView2);
myButton2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String time = number.getText().toString();
display.setText(time);
}
});
myButton1 = (Button) findViewById(R.id.myButton);
myButton1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
time = Integer.valueOf(number.getText().toString());
open_activity2();
}
});
}
public void open_activity2() {
Intent intent = new Intent(this, Activity2.class);
intent.putExtra("Time", time);
startActivity(intent);
}
}
Activity2 的代码：
public class Activity2 extends AppCompatActivity {
private SoundPool soundPool;
private int sound1, sound2, sound3;
private Bundle b;
private int timeCycle;
private TextView displayNotes;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_2);
displayNotes = (TextView) findViewById(R.id.textView);
b = getIntent().getExtras();
timeCycle = b.getInt("Time");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
AudioAttributes audioAttributes = new AudioAttributes.Builder()
.setUsage(AudioAttributes.USAGE_ASSISTANCE_SONIFICATION)
.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
.build();
soundPool = new SoundPool.Builder()
.setMaxStreams(5)
.setAudioAttributes(audioAttributes)
.build();
} else {
soundPool = new SoundPool(5, AudioManager.STREAM_MUSIC, 0);
}
sound1 = soundPool.load(this, R.raw.sound1, 1);
sound2 = soundPool.load(this, R.raw.sound2, 1);
sound3 = soundPool.load(this, R.raw.sound3, 1);
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
for (int i = 0; i < 10; i++) {
try {
TimeUnit.SECONDS.sleep(timeCycle);
runOnUiThread(new Runnable() {
@Override
public void run() {
randomNote();
}
});
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}, 0);
}
protected void randomNote () {
Random r = new Random();
int randomNumber = r.nextInt(3);
switch (randomNumber) {
case 0:
soundPool.play(sound1, 1, 1, 1, 0, 1);
displayNotes.setText("Note: C");
break;
case 1:
soundPool.play(sound2, 1, 1, 1, 0, 1);
displayNotes.setText("Note: D");
break;
case 2:
soundPool.play(sound3, 1, 1, 1, 0, 1);
displayNotes.setText("Note: E");
break;
}
}
@Override
protected void onDestroy() {
super.onDestroy();
soundPool.release();
soundPool = null;
}
}
我收到的错误消息，搜索了 XX 和异常之类的内容，但没有找到任何内容：

你是运行
for (int i = 0; i < 10; i++) {
try {
TimeUnit.SECONDS.sleep(timeCycle);
randomNote();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
在 UI 线程上。这导致 UI 更改冻结，直到循环完成。如果你想有一个活动的 UI while 运行 这个代码，你使用 Handler:
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
for (int i = 0; i < 10; i++) {
try {
TimeUnit.SECONDS.sleep(timeCycle);
runOnUiThread(new Runnable() {
@Override
public void run() {
randomNote();
}
});
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}, 0);

你是运行

在 UI 线程上。这导致 UI 更改冻结，直到循环完成。如果你想有一个活动的 UI while 运行 这个代码，你使用 Handler:
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
for (int i = 0; i < 10; i++) {
try {
TimeUnit.SECONDS.sleep(timeCycle);
runOnUiThread(new Runnable() {
@Override
public void run() {
randomNote();
}
});
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}, 0);
