1、自定义布局（密码框、对话框等等）
2、从下往上弹出效果的实现
一、对话框
第一步：
Xml代码：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="vertical"
>
<LinearLayout
android:id="@+id/pop_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="vertical"
android:layout_alignParentBottom="true"
android:background="@drawable/btn_style_alert_dialog_background"
>
<Button
android:id="@+id/btn_take_photo"
android:layout_marginLeft="20dip"
android:layout_marginRight="20dip"
android:layout_marginTop="20dip"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="拍照"
android:background="@drawable/btn_style_alert_dialog_button"
android:textStyle="bold"
/>
<Button
android:id="@+id/btn_pick_photo"
android:layout_marginLeft="20dip"
android:layout_marginRight="20dip"
android:layout_marginTop="5dip"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="从相册选择"
android:background="@drawable/btn_style_alert_dialog_button"
android:textStyle="bold"
/>
<Button
android:id="@+id/btn_cancel"
android:layout_marginLeft="20dip"
android:layout_marginRight="20dip"
android:layout_marginTop="15dip"
android:layout_marginBottom="15dip"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="取消"
android:background="@drawable/btn_style_alert_dialog_cancel"
android:textColor="#ffffff"
android:textStyle="bold"
/>
</LinearLayout>
</RelativeLayout>
第二步：创建SelectPicPopupWindow类继承PopupWindow：
import android.app.Activity;
import android.content.Context;
import android.graphics.drawable.ColorDrawable;
import android.view.LayoutInflater;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.View.OnTouchListener;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.widget.PopupWindow;
public class SelectPicPopupWindow extends PopupWindow {
private Button btn_take_photo, btn_pick_photo, btn_cancel;
private View mMenuView;
public SelectPicPopupWindow(Activity context,OnClickListener itemsOnClick) {
super(context);
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mMenuView = inflater.inflate(R.layout.alert_dialog, null);
btn_take_photo = (Button) mMenuView.findViewById(R.id.btn_take_photo);
btn_pick_photo = (Button) mMenuView.findViewById(R.id.btn_pick_photo);
btn_cancel = (Button) mMenuView.findViewById(R.id.btn_cancel);
//取消按钮
btn_cancel.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
//销毁弹出框
dismiss();
}
});
//设置按钮监听
btn_pick_photo.setOnClickListener(itemsOnClick);
btn_take_photo.setOnClickListener(itemsOnClick);
//设置SelectPicPopupWindow的View
this.setContentView(mMenuView);
//设置SelectPicPopupWindow弹出窗体的宽
this.setWidth(LayoutParams.FILL_PARENT);
//设置SelectPicPopupWindow弹出窗体的高
this.setHeight(LayoutParams.WRAP_CONTENT);
//设置SelectPicPopupWindow弹出窗体可点击
this.setFocusable(true);
//设置SelectPicPopupWindow弹出窗体动画效果
this.setAnimationStyle(R.style.AnimBottom);
//实例化一个ColorDrawable颜色为半透明
ColorDrawable dw = new ColorDrawable(0xb0000000);
//设置SelectPicPopupWindow弹出窗体的背景
this.setBackgroundDrawable(dw);
//mMenuView添加OnTouchListener监听判断获取触屏位置如果在选择框外面则销毁弹出框
mMenuView.setOnTouchListener(new OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
int height = mMenuView.findViewById(R.id.pop_layout).getTop();
int y=(int) event.getY();
if(event.getAction()==MotionEvent.ACTION_UP){
if(y<height){
dismiss();
}
}
return true;
}
});
}
}
第三步：编写MainActivity类实现测试：
import android.app.Activity;
import android.os.Bundle;
import android.view.Gravity;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.TextView;
public class MainActivity extends Activity {
//自定义的弹出框类
SelectPicPopupWindow menuWindow;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView tv = (TextView) this.findViewById(R.id.text);
//把文字控件添加监听，点击弹出自定义窗口
tv.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
//实例化SelectPicPopupWindow
menuWindow = new SelectPicPopupWindow(MainActivity.this, itemsOnClick);
//显示窗口
menuWindow.showAtLocation(MainActivity.this.findViewById(R.id.main), Gravity.BOTTOM|Gravity.CENTER_HORIZONTAL, 0, 0); //设置layout在PopupWindow中显示的位置
}
});
}
//为弹出窗口实现监听类
private OnClickListener itemsOnClick = new OnClickListener(){
public void onClick(View v) {
menuWindow.dismiss();
switch (v.getId()) {
case R.id.btn_take_photo:
break;
case R.id.btn_pick_photo:
break;
default:
break;
}
}
};
}
二、密码框
自定义密码框xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/colorPrimary"

android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_height="50dp">
<ImageView
android:id="@+id/iv_pay_back"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="10dp" />
<TextView
android:id="@+id/tv_pay_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:layout_marginLeft="15dp"
android:layout_marginTop="15dp"
android:text="@string/pin_id"
android:textColor="@color/white"
android:textSize="18dp" />
</RelativeLayout>
<!-- 6位密码框布局，需要一个圆角边框的shape作为layout的背景 -->
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:gravity="center"

自定义popwind

<com.view.PasswordView
android:id="@+id/pv_pop_win"
android:layout_width="match_parent"
android:layout_height="match_parent">
</com.view.PasswordView>
</LinearLayout>
使用：
private static PopupWindow mPopupWindow;
private static View popView;
private static PasswordView mPasswordView;
popView = View.inflate(context, R.layout.pop_window, null);
mPopupWindow = new PopupWindow(popView, ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT);
mPopupWindow.setTouchable(true);
mPopupWindow.setOutsideTouchable(true);
mPopupWindow.setBackgroundDrawable(new BitmapDrawable());
// 设置动画
mPopupWindow.setAnimationStyle(R.style.mypopwindow_anim_style);
mPopupWindow.getContentView().setFocusableInTouchMode(true);
mPopupWindow.getContentView().setFocusable(true);
mPopupWindow.showAtLocation(view, Gravity.CENTER, 0, 0);
// mPopupWindow.showAsDropDown(controlPager,0,0);
mPasswordView = (PasswordView) popView.findViewById(R.id.pv_pop_win);
// mPasswordView.getTitle().setText(getString(R.string.pin_id));
mPasswordView.setOnFinishInput(new PasswordView.OnPasswordInputFinish() {
@Override
public void inputFinish() {

lock.setMove(true);
//验证车辆密码
// checkCarPwd(mPasswordView.getPassword());
if (mPasswordView.getPassword().equals(AppConfig.getInstance().getString("key", ""))) {
//密码正确
listener.onSuccess();
} else {
//密码错误
listener.onError();
}
}
});
mPasswordView.setCancelListener(new PasswordView.OnCancelListener() {
@Override
public void OnCancel() {
lock.setMove(true);
mPopupWindow.dismiss();
}
});
