Android自定义Dialog以控制其位置和宽高

1.自定义Dialog类

import android.app.Dialog;import android.content.Context;import android.view.Gravity;import android.view.View;import android.view.Window;import android.view.WindowManager;/** * Created by yechaoa on 2016/10/22. */public class MyDialog extends Dialog {    private Window window = null;    public MyDialog(Context context, boolean cancelable,                    OnCancelListener cancelListener) {        super(context, cancelable, cancelListener);    }    public MyDialog(Context context, int theme) {        super(context, theme);    }    public MyDialog(Context context) {        super(context);    }    public void setView(View view) {        setContentView(view);    }    public void setView(int id) {        setContentView(id);    }    public void setProperty(int x, int y, int w, int h) {        window = getWindow();//得到对话框的窗口．        WindowManager.LayoutParams wl = window.getAttributes();        wl.x = x;//设置对话框的位置．0为中间        wl.y = y;        wl.width = w;        wl.height = h;        wl.alpha = 1f;// 设置对话框的透明度,1f不透明        wl.gravity = Gravity.CENTER;//设置显示在中间        window.setAttributes(wl);    }}

2.给dialog一个style

3.圆角白底xml文件

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

4.dialog的使用

final MyDialog dialog=new MyDialog(MainActivity.this, R.style.myDialog);        final View view = View.inflate(ManifestEditActivity.this, R.layout.dialog_submit,null);        dialog.setView(view);        dialog.setProperty(0,0, 600, 400);//设置坐标和宽高        dialog.setCanceledOnTouchOutside(true);        dialog.show();        Button dialogCancel= (Button) view.findViewById(R.id.dialog_cancel);        dialogCancel.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                dialog.dismiss();            }        });        Button dialogConfirm= (Button) view.findViewById(R.id.dialog_confirm);        dialogConfirm.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {               //doSomething                            }        });
