Answer 1

只需在OnCreate（）

中的splashScreen.java中替换这4行

   requestWindowFeature(Window.FEATURE_NO_TITLE);  
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                  WindowManager.LayoutParams.FLAG_FULLSCREEN);
        super.onCreate(savedInstanceState);
        setContentView(R.layout.splash_layout);

Answer 2

在oncreate中添加这些行

requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
        WindowManager.LayoutParams.FLAG_FULLSCREEN);

使用此

 <activity
            android:name=".SplashScreen"
            android:label="@string/app_name"
            android:theme="@android:style/Theme.NoTitleBar.Fullscreen" 
             >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

Answer 3

在您的启动画面启动器活动

中

super.onCreate(savedInstanceState);
     requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
    WindowManager.LayoutParams.FLAG_FULLSCREEN);
  setContentView(R.layout.splash_layout);

更改您的启动画面启动器活动后

import android.support.v7.app.ActionBarActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.Window;
import android.view.WindowManager;

public class SplashScreen extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
         requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
        WindowManager.LayoutParams.FLAG_FULLSCREEN);
      setContentView(R.layout.splash_layout);
         final int welcomeScreenDisplay = 3000;
            /** create a thread to show splash up to splash time */
            Thread welcomeThread = new Thread() {

            int wait = 0;

            @Override
            public void run() {
            try {
            super.run();
            /**
            * use while to get the splash time. Use sleep() to increase
            * the wait variable for every 100L.
            */
            while (wait < welcomeScreenDisplay) {
            sleep(100);
            wait += 100;

            }
            } catch (Exception e) {
            System.out.println("EXc=" + e);
            } finally {
            /**
            * Called after splash times up. Do some action after splash
            * times up. Here we moved to another main activity class
            */
            startActivity(new Intent(SplashScreen.this,LoginActivity.class));
            finish();
            }
            }
            };
            welcomeThread.start();
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.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();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}
