Android，页面3秒自东跳转和点击跳转显示

先打开ADT程序创建

创建文件：如图

命名为Day01（注意大小写）

注意改名字不要重复

 

 

在res—layout中找到

下面第一个是视图，第二个是对视图进行编辑点击第二个进行编辑

把<RelativeLayout>改成<LinearLayout>代码如下

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".SecondActivity" >

</LinearLayout>

 

创建好这些java和xml

 

 

找到这个位置把图片拉进去 

 然后在他对应的类中开始写跳转代码

 在下图类中写图下页面三秒跳转代码

 

package com.example.day;

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;

public class InfoActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_info);
		//1:定一个子线程
		
		Thread t= new Thread(new Runnable() {
			
			@Override
			public void run() {
				//1:休眠3S
				try {
					Thread.sleep(3000);
				} catch (InterruptedException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
				
				//2:开启新的activity页面
				Intent it=new Intent(getApplicationContext(),
						MainActivity.class);
				startActivity(it);
			}
		});
		//2:启动这个子线程
		t.start();
	}

}

Thread.sleep(3000);会报错抛出异常即可鼠标放错误方面点击try/catch

然后在中写入

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
	android:background="@drawable/ic_launcher"
    tools:context=".InfoActivity" >


</RelativeLayout>

 重点是android:background="@drawable/ic_launcher"加入图片

在activity_main.xml中编写代码.

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

            android:textColor="#fff" />
    </LinearLayout>

            android:background="@drawable/et_1"
            android:text="取消" />
    </LinearLayout>

</LinearLayout>

注意下拉列表

 

 然后在第二个类定义id内容和跳转到另一个界面

package com.example.day;

import android.R.anim;
import android.os.Bundle;
import android.provider.Settings.System;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.RadioButton;
import android.widget.Spinner;

public class MainActivity<spItem> extends Activity implements OnClickListener {
	// 1:定义所有控件
	private EditText etZh, etMm, etBj;
	private RadioButton rbM, rbW;
	private CheckBox cb1, cb2, cb3;
	private Button btnQd, btnQx;
	private Spinner spItem;
	String[]str=null;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		// 2:找到所有有id的控件
		init();

		// 3:设置点击按钮的点击事件
		btnQd.setOnClickListener(this);
		// 准备控件所要显示的数据
		str= new String[]{ "移动212", "移动213", "移动214", "移动215" };
		// 使用适配器来进行页面和数据的绑定
		ArrayAdapter<String> adapter = new ArrayAdapter<String>(
				getApplicationContext(), R.layout.item1,
				str);
		spItem.setAdapter(adapter);
	}
        //找到这些控件
	private void init() {
		etZh = (EditText) findViewById(R.id.et_zh);
		etMm = (EditText) findViewById(R.id.et_mm);
		rbM = (RadioButton) findViewById(R.id.rb_m);
		rbW = (RadioButton) findViewById(R.id.rb_w);
		cb1 = (CheckBox) findViewById(R.id.cb_1);
		cb2 = (CheckBox) findViewById(R.id.cb_2);
		cb3 = (CheckBox) findViewById(R.id.cb_3);
		btnQd = (Button) findViewById(R.id.btn_qd);
		btnQx = (Button) findViewById(R.id.btn_qx);
		spItem = (Spinner) findViewById(R.id.sp_item);
	}

	@Override
	public void onClick(View arg0) {
		// 4： 获取用户名输入框
		String zh = etZh.getText().toString();
		// 5：获取密码输入框内容
		String mm = etMm.getText().toString();
		// 6：获取性别单选框内容
		String sex = "";
		if (rbM.isClickable()) {
			sex = rbM.getText().toString();
		}
		if (rbW.isClickable()) {
			sex = rbW.getText().toString();
		}
		// 7：获取爱好多选框内容
		String fav = "";
		if (cb1.isChecked()) {
			fav += cb1.getText().toString();
		}
		if (cb2.isChecked()) {
			fav += cb2.getText().toString();
		}
		if (cb3.isChecked()) {
			fav += cb3.getText().toString();
		}
		//7.2获取下拉列表选中的内容
		int i=spItem.getSelectedItemPosition();
		String spItem=str[i];

		// 8:传值跳转
		Intent it = new Intent(getApplicationContext(), SecondActivity.class);
		// 9:传递数据！！！
		it.putExtra("zh", zh);
		it.putExtra("mm", mm);
		it.putExtra("sex", sex);
		it.putExtra("fav", fav);
		it.putExtra("spItem",spItem);
		startActivity(it);
	}
}

 我们开始跳转最后一个页面

代码如下记得加id因为会用到

 

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".SecondActivity" >

    <TextView
        android:id="@+id/tv_show"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

</RelativeLayout>

 跳转传输的数据的第三个类     

package com.example.day505;

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.widget.TextView;
import android.widget.Toast;

public class SecondActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_second);
		
		//获取上一页面传递的数据
		Intent it = getIntent();
		
		String zh = it.getStringExtra("zh");
		String mm = it.getStringExtra("mm");
		String sex = it.getStringExtra("sex");
		String fav = it.getStringExtra("fav");
		String spItem = it.getStringExtra("spItem");
		String str = zh+":"+mm+":"+sex+":"+fav+":"+spItem;
		//显示这些数据
		//1.吐司显示
		Toast.makeText(getApplicationContext(), str, 1).show();
		//2.文本框显示
		TextView tvShow = (TextView) findViewById(R.id.tv_show);
		tvShow.setText(str);
	}
}
