主页面 功能代码:Maintivity.java

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

    public void testOne(View view){
        Intent intent = new Intent(this,TestOneActivity.class);
        startActivity(intent);

一、手机拔号,邮箱发件,链接地址

只要在autoLink 这里设置 就可以使用了。



代码:TestOneActivity.java

没有什么代码

package com.open_open.uizujian;

import android.app.Activity;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class TestOneActivity extends Activity {

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


页面:activity_test_one

<?xml version="1.0" encoding="utf-8"?>
<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:orientation="vertical">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="这是一个文本"
        android:background="@android:color/holo_blue_light"
        style="@style/myTextVied"/>

    android:autoLink="web"
    style="@style/myTextVied"/>

</LinearLayout>


二、这是一个稍微严格的注册页面,也比较人性化

用户名获取焦点的时候,自动切换全键盘26格,

输入密码 和年龄的 的时候:切换密码9格键,输入变点(年龄除外),

地址:考虑较长,设置多行显示




并做了传参,可接受输入信息

三、Button 按钮

圆形,复选框,普通按钮,图片按钮




通过图片按钮可获取值

            }
        });
    }

//取值[单选按钮|复选框]

        RadioButton rb=(RadioButton)findViewById(rg.getCheckedRadioButtonId());

        StringBuffer sb=new StringBuffer();

        sb.append("性别:"+rb.getText().toString()+"\n");

//复选框
        sb.append("爱好:");
        if(cb1.isChecked())
            sb.append(cb1.getText().toString()+",");
        if(cb2.isChecked())

<resources>
    <style name="myButton" parent="android:Widget.Button">
        <item name="android:textSize">28sp</item>

        <item name="android:gravity">center</item>
        <item name="android:layout_margin">5sp</item>
    </style>

    <style name="myTextVied" parent="android:Widget.TextView">
        <item name="android:textSize">28sp</item>
        <item name="android:textColor">@color/test_hui</item>
