Question

我的应用程序在开始时崩溃了。 logcat指向此行setContentView(R.layout.activity_splash);。我是android的新手，现在已经差不多两个小时就遇到了这个问题。

的活动：

public class SplashActivity extends ActionBarActivity {

    /** Duration of wait **/
    private final int SPLASH_DISPLAY_LENGTH = 1000;


    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.activity_splash);

        /* New Handler to start the Menu-Activity
         * and close this Splash-Screen after some seconds.*/
        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                /* Create an Intent that will start the Menu-Activity. */
                Intent mainIntent = new Intent(SplashActivity.this, LogInActivity.class);
                SplashActivity.this.startActivity(mainIntent);
                SplashActivity.this.finish();
            }
        }, SPLASH_DISPLAY_LENGTH);
    }





}

Xml布局：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:src="@drawable/splash"
        android:id="@+id/splash"
        />






</LinearLayout>

logcat的：

Answer 1

更改您的代码。而不是

public class SplashActivity extends Activity

写

public class SplashActivity extends ActionBarActivity {

Answer 2

在themes.xml：

中尝试使用此配置

<style name="MyTheme" parent="Theme.AppCompat">
    ...
</style>

<style name="MyTheme.NoActionBar">
    <!-- Both of these are needed -->
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

我不能让我的启动画面工作，应用程序崩溃开始
