上午写了一篇博文，介绍了如何定义从屏幕底部弹出PopupWindow，写完之后，突然想起之前写过自定义内容显示的弹出框，就随手写了两个实例，分享出来：
第一种实现方式：继承Dialog
1.1 线定义弹出框要显示的内容：create_user_dialog.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/create_user_dialog_view"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/dialog_load_bg"
android:minWidth="200dp"
android:orientation="vertical"
android:padding="10dp"
android:paddingBottom="30dp"
android:paddingTop="30dp">
<EditText
android:id="@+id/text_name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/edit_bg"
android:hint="姓名"
android:minHeight="45dp"
android:textSize="18sp" />
<EditText
android:id="@+id/text_mobile"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:background="@drawable/edit_bg"
android:hint="手机号"
android:minHeight="45dp"
android:textSize="18sp" />
<EditText
android:id="@+id/text_info"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:background="@drawable/edit_bg"
android:gravity="top|left"
android:hint="个性签名"
android:minHeight="145dp"
android:textSize="18sp" />
<Button
android:id="@+id/btn_save_pop"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:text="保存" />
</LinearLayout>
1.2 定义要弹出的Dialog
public class CreateUserDialog extends Dialog {
/**
* 上下文对象 *
*/
Activity context;
private Button btn_save;
public EditText text_name;
public EditText text_mobile;
public EditText text_info;
private View.OnClickListener mClickListener;
public CreateUserDialog(Activity context) {
super(context);
this.context = context;
}
public CreateUserDialog(Activity context, int theme, View.OnClickListener clickListener) {
super(context, theme);
this.context = context;
this.mClickListener = clickListener;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// 指定布局
this.setContentView(R.layout.create_user_dialog);
text_name = (EditText) findViewById(R.id.text_name);
text_mobile = (EditText) findViewById(R.id.text_mobile);
text_info = (EditText) findViewById(R.id.text_info);
/*
* 获取圣诞框的窗口对象及参数对象以修改对话框的布局设置, 可以直接调用getWindow(),表示获得这个Activity的Window
* 对象,这样这可以以同样的方式改变这个Activity的属性.
*/
Window dialogWindow = this.getWindow();
WindowManager m = context.getWindowManager();
Display d = m.getDefaultDisplay(); // 获取屏幕宽、高用
WindowManager.LayoutParams p = dialogWindow.getAttributes(); // 获取对话框当前的参数值
// p.height = (int) (d.getHeight() * 0.6); // 高度设置为屏幕的0.6
p.width = (int) (d.getWidth() * 0.8); // 宽度设置为屏幕的0.8
dialogWindow.setAttributes(p);
// 根据id在布局中找到控件对象
btn_save = (Button) findViewById(R.id.btn_save);
// 为按钮绑定点击事件监听器
btn_save.setOnClickListener(mClickListener);
this.setCancelable(true);
}
} 1.3 调用弹出框：
public void showEditDialog(View view) {
createUserDialog = new CreateUserDialog(this,R.style.loading_dialog,onClickListener);
createUserDialog.show();
}
private View.OnClickListener onClickListener = new View.OnClickListener() {
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btn_save:
String name = createUserDialog.text_name.getText().toString().trim();
String mobile = createUserDialog.text_mobile.getText().toString().trim();
String info = createUserDialog.text_info.getText().toString().trim();
System.out.println(name+"——"+mobile+"——"+info);
break;
}
}
};
第二种实现方式：继承PopupWindow
2.1 定义弹出框布局文件，和1.1定义的一致
2.2 定义要弹出的PopupWindow
public class CreateUserPopWin extends PopupWindow {
private Context mContext;
private View view;
private Button btn_save_pop;
public EditText text_name;
public EditText text_mobile;
public EditText text_info;
public CreateUserPopWin(Activity mContext, View.OnClickListener itemsOnClick) {
this.mContext = mContext;
this.view = LayoutInflater.from(mContext).inflate(R.layout.create_user_pop, null);
text_name = (EditText) view.findViewById(R.id.text_name);
text_mobile = (EditText) view.findViewById(R.id.text_mobile);
text_info = (EditText) view.findViewById(R.id.text_info);
btn_save_pop = (Button) view.findViewById(R.id.btn_save_pop);
// 设置按钮监听
btn_save_pop.setOnClickListener(itemsOnClick);
// 设置外部可点击
this.setOutsideTouchable(true);
/* 设置弹出窗口特征 */
// 设置视图
this.setContentView(this.view);
// 设置弹出窗体的宽和高
/*
* 获取圣诞框的窗口对象及参数对象以修改对话框的布局设置, 可以直接调用getWindow(),表示获得这个Activity的Window
* 对象,这样这可以以同样的方式改变这个Activity的属性.
*/
Window dialogWindow = mContext.getWindow();
WindowManager m = mContext.getWindowManager();
Display d = m.getDefaultDisplay(); // 获取屏幕宽、高用
WindowManager.LayoutParams p = dialogWindow.getAttributes(); // 获取对话框当前的参数值
this.setHeight(RelativeLayout.LayoutParams.WRAP_CONTENT);
this.setWidth((int) (d.getWidth() * 0.8));
// 设置弹出窗体可点击
this.setFocusable(true);
}
}
2.3 调用该弹框组件
public void showEditPopWin(View view) {
createUserPopWin = new CreateUserPopWin(this,onClickListener);
createUserPopWin.showAtLocation(findViewById(R.id.main_view), Gravity.CENTER, 0, 0);
}
private View.OnClickListener onClickListener = new View.OnClickListener() {
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btn_save_pop:
String name1 = createUserPopWin.text_name.getText().toString().trim();
String mobile1 = createUserPopWin.text_mobile.getText().toString().trim();
String info1 = createUserPopWin.text_info.getText().toString().trim();
System.out.println(name1+"——"+mobile1+"——"+info1);
createUserPopWin.dismiss();
break;
}
}
};
