我正在尝试使用android studio创建启动画面。但是我在启动时遇到错误。它说不幸的是app_name已经停止了。
splashscreen.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/colorPrimary" >
<ImageView
android:id="@+id/imgLogo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:src="@drawable/logo" />
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:textSize="12dp"
android:textColor="#454545"
android:gravity="center_horizontal"
android:layout_alignParentBottom="true"
android:text="OK Google" />
</RelativeLayout>
SplashScreen.java
public class SplashScreen extends Activity
{
// Splash screen timer
private static int SPLASH_TIME_OUT = 8000;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splashscreen);
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
// This method will be executed once the timer is over
// Start your app main activity
Intent i = new Intent(SplashScreen.this, MainActivity.class);
startActivity(i);
// close this activity
finish();
}
}, SPLASH_TIME_OUT);
}
}
的AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.sloid.splashgun">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity
android:name="com.example.sloid.splashgun.SplashScreen"
android:label="@string/app_name"

android:theme="@style/SplashTheme" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />

</intent-filter>
</activity>
<activity android:name="com.example.sloid.splashgun.MainActivity"
android:label="@string/app_name"/>
</application>
</manifest>
我想创建一个启动画面并运行8秒。我想显示我的徽标和一些文字
错误说不幸app_name已停止。它关闭。
请帮忙。

import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
@Override

您可以使用此代码执行您想要的操作。我在我的应用程序中使用它，如果问题不在于你的MainActivity，那么它可以正常工作
public class SplashActivity extends Activity implements Runnable {
Thread mThread;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splashScreen);
mThread = new Thread(this);
mThread.start();
}
@Override
public void run(){
try {
Thread.sleep(8000);
}
catch (Exception e) {
e.printStackTrace();
}
finally {
startActivity(new Intent(getApplicationContext(), MainActivity.class));
finish();
}
}
}

您的代码看起来很好。错误是设备内存不足。其中一个原因可能是您的可绘制文件夹中的徽标文件太大。
您也可以尝试在具有更多可用内存的设备上运行此代码以进行确认。
