android-弹出窗口的使用（1）

android几种常见弹出窗口实现如下：

public class AndroidLearn extends Activity {

EditText pwdText ;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_android_learn);

/*1、不带输入框的弹出窗口，可用于提醒等功能*/
Button btn1 = (Button) findViewById(R.id.button1);
btn1.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
AlertDialog.Builder dialog = new AlertDialog.Builder(AndroidLearn.this);
//dialog.setIcon(R.drawable.ic_launcher);//窗口头图标
dialog.setTitle("提示");//窗口名
dialog.setMessage("是否退出应用程序 ");
dialog.setPositiveButton("确定",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub

}
});
dialog.setNegativeButton("取消",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub

}
});
//dialog.setNeutralButton("中间按钮",new DialogInterface.OnClickListener() {
//public void onClick(DialogInterface dialog, int which) {
//// TODO Auto-generated method stub
//
//}
//});
dialog.show();
}
});

/*2、带简单输入框的弹出对话框*/
Button btn2 = (Button) findViewById(R.id.button2);
btn2.setOnClickListener(new OnClickListener() {

public void onClick(View v) {

final EditText edit = new EditText(AndroidLearn.this);
AlertDialog.Builder dialog = new AlertDialog.Builder(AndroidLearn.this);
//dialog.setIcon(R.drawable.ic_launcher);//窗口头图标
dialog.setTitle("请输入密码");//窗口名
dialog.setView(edit);

dialog.setPositiveButton("确定",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
System.out.println(edit.getText().toString());
}
});
dialog.setNegativeButton("取消",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
}
});
dialog.show();
}
});


/*3、自定义弹出对话框*/
Button btn3 = (Button) findViewById(R.id.button3);
btn3.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
LayoutInflater flater = getLayoutInflater();
View view =  flater.inflate(R.layout.self_layout, (ViewGroup) findViewById(R.id.dialog));
final EditText name = (EditText) view.findViewById(R.id.name);
final EditText pwd = (EditText) view.findViewById(R.id.password);
AlertDialog.Builder dialog = new AlertDialog.Builder(AndroidLearn.this);
dialog.setIcon(R.drawable.ic_launcher);//窗口头图标
dialog.setTitle("自定义对话框");//窗口名
dialog.setMessage("这是简单例子");//窗口信息
dialog.setView(view);

dialog.setPositiveButton("确定",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {

System.out.println("enter name =="+name.getText().toString());
System.out.println("enter  pwd =="+pwd.getText().toString());

}
});
dialog.setNegativeButton("取消",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
}
});
dialog.show();
}
});

/*4、单选弹出对话框*/
Button btn4 = (Button) findViewById(R.id.button4);
btn4.setOnClickListener(new OnClickListener() {
public void onClick(View v) {

AlertDialog.Builder dialog = new AlertDialog.Builder(AndroidLearn.this);
dialog.setIcon(android.R.drawable.ic_dialog_info);//窗口头图标
dialog.setTitle("单选框");//窗口名
dialog.setSingleChoiceItems(new String[]{"Item1", "Item2"}, 0,new DialogInterface.OnClickListener() {
      public void onClick(DialogInterface dialog, int which) {      
      System.out.println("选择第"+which+"个");      
      }} );

dialog.setNegativeButton("取消", null);
dialog.show();
}
});

/*4、多选弹出对话框*/
Button btn5 = (Button) findViewById(R.id.button5);
btn5.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
AlertDialog.Builder dialog = new AlertDialog.Builder(AndroidLearn.this);
dialog.setIcon(android.R.drawable.ic_dialog_info);//窗口头图标
dialog.setTitle("多选框");//窗口名
dialog.setMultiChoiceItems(new String[]{"Item1", "Item2"},new boolean[]{false,false} ,new DialogInterface.OnMultiChoiceClickListener() {

@Override
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
// TODO Auto-generated method stub

}
});
dialog.setNegativeButton("取消", null);
dialog.show();

}
});
}
}

三种布局文件如下：

activity_android_learn.xml文件如下：

<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"
    tools:context=".AndroidLearn" >

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:text="简单对话框" />

    <Button
        android:id="@+id/button2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignRight="@+id/button1"
        android:layout_below="@+id/button1"

    <Button
        android:id="@+id/button3"
        android:layout_width="wrap_content"

        android:layout_alignRight="@+id/button2"
        android:layout_below="@+id/button2"
        android:text="自定义对话框" />

        <Button
        android:id="@+id/button4"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignRight="@+id/button2"
        android:layout_below="@+id/button3"
        android:text="单选对话框" />
        
        <Button
        android:id="@+id/button5"

        android:layout_alignParentLeft="true"
        android:layout_alignRight="@+id/button2"
        android:layout_below="@+id/button4"

   android:text="姓名：" />
 <EditText
     android:id="@+id/etname"
     android:layout_width="278dp"
     android:layout_height="wrap_content"
     android:minWidth="100dip" />
</LinearLayout>

self_layout.xml布局文件如下：

<?xml version="1.0" encoding="UTF-8"?>
  
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"  
    android:layout_width="fill_parent"
     android:layout_height="wrap_content"  
      android:background="@drawable/back"
       
    android:orientation="vertical">

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="用户名"
        android:textAppearance="?android:attr/textAppearanceLarge" />

    <EditText
        android:id="@+id/name"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:ems="10"
        android:inputType="none" >
    </EditText>
    
        <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
