每次运行模拟器并运行应用程序时，我都会遇到Android工作室启动画面的问题，它会在启动画面后停止。我的SplashScreen.java代码从我从别人那里看到的看起来很好。我相信问题在于清单，但似乎无法弄明白。 logcat没有显示任何问题。我被卡住了，所以任何帮助都会受到赞赏。
?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.mook.bodyshop">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="Don's Body Shop"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".SplashScreen">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="com.example.mook.bodyshop.MainActivity"></activity>
</application>
这就是清单。这是SplashScreen.java
import java.util.Timer;
import java.util.TimerTask;
public class SplashScreen extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash_screen);
/*Thread myThread = new Thread(){
@Override
public void run() {
try {
sleep(1000);
Intent intent = new Intent(SplashScreen.this, MainActivity.class);
startActivity(intent);
finish();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
};
myThread.start();*/
TimerTask task = new TimerTask() {
@Override
public void run() {
startActivity(new Intent(SplashScreen.this, MainActivity.class));
finish();
}
};
Timer opening = new Timer();
opening.schedule(task, 5000);
}
}
然后这是我的MainActivity.java
package com.example.mook.bodyshop;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
最后是logcat。

答案 0 :(得分：0)
我只是回答我自己的问题！问题是SplashScreen的扩展程度与MainActivity不同。
public class SplashScreen extends Activity
public class MainActivity extends AppCompatActivity
因此我将它们都延伸Activity，因为当我延长AppCompatActivity时，它仍然会在SplashScreen之后停止。
