注意点:引导页的图片不能太大,否则无法显示出来,之前自己弄了一张4M多的图片,就显示不了。
步骤1、新建WelCome Activity页
在WelCome XML Code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
tools:context="cn.cgrs.myphone.Welcome">
<ImageView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@mipmap/welcome"
android:tintMode="screen"
android:fitsSystemWindows="true"
/>
</RelativeLayout>
在WelCome 后台代码:
package cn.cgrs.myphone;
import android.content.Intent;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.widget.ImageView;
import android.widget.Toast;
public class Welcome extends AppCompatActivity {
//延迟时间
private static final int TIME = 2000;
private Handler mHander = new Handler(){
@Override
public void handleMessage(android.os.Message msg) {
goHome();
};
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_welcome);
//Toast.makeText(this, "OKOKOK!", Toast.LENGTH_LONG).show();
mHander.sendEmptyMessageDelayed(0,TIME);
}
private void goHome()
{
Intent intent = new Intent(Welcome.this,MainActivity.class);
startActivity(intent);
this.finish();
}
}
MainActivity为主页面
