阅读更多

本文简单实现常用客户登录界面,如qq,微薄等客户端登录。

短暂停留界面:



登录界面:


实现比较简单,首先是短暂停留界面布局:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
    <ImageView
        android:layout_width ="fill_parent"
        android:layout_height ="fill_parent"
        android:scaleType ="fitXY"
        android:src ="@drawable/splash" />
</LinearLayout>
该界面对应的Activity:

/**
 * 应用启动短暂停留界面
 * @author builder
 *
 */
public class SplashActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.splash);
		new Handler().postDelayed(new Runnable() {
              public void run() {
                   Intent intent=new Intent(SplashActivity.this,LoginActivity.class);
                   startActivity(intent);
                   SplashActivity.this.finish();//结束本Activity
              }
        }, 1000);//设置执行时间
	}
}
登录界面布局:

<RelativeLayout xmlns:android ="http://schemas.android.com/apk/res/android"
    xmlns:tools= "http://schemas.android.com/tools"
    android:layout_width= "match_parent"
