简单的dialog菜单

本文介绍的是我自己做的一个简单的dialog菜单,可以直接植入到类中。

方法代码:

/** 显示一个靠右上的dialog列表菜单*/
private void showTopBarRightButtonDropListDialog() {   final Dialog dialog = new Dialog(this, R.style.DialogStyle);   LinearLayout linearLayout = new LinearLayout(this);   linearLayout.setOrientation(LinearLayout.VERTICAL);   ViewGroup.LayoutParams params0 = new ViewGroup.LayoutParams(200, ViewGroup.LayoutParams.WRAP_CONTENT);   linearLayout.setLayoutParams(params0);   // 获取屏幕的信息   DisplayMetrics dm = new DisplayMetrics();   getWindowManager().getDefaultDisplay().getMetrics(dm);   // 添加子视图   Button btn1 = new Button(this);   Button btn2 = new Button(this);   Button btn3 = new Button(this);   Button btn4 = new Button(this);   Button btn5 = new Button(this);   btn1.setText("1");   btn2.setText("2");   btn3.setText("3");   btn4.setText("4");   btn5.setText("5");   LinearLayout.LayoutParams params1 = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, (int)(50 * dm.density));   btn1.setLayoutParams(params1);   btn2.setLayoutParams(params1);   btn3.setLayoutParams(params1);   btn4.setLayoutParams(params1);   btn5.setLayoutParams(params1);   btn1.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { dialog.dismiss(); } }); btn2.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { dialog.dismiss(); } }); btn3.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { dialog.dismiss(); } }); linearLayout.addView(btn1); linearLayout.addView(btn2); linearLayout.addView(btn3); linearLayout.addView(btn4); linearLayout.addView(btn5); dialog.setContentView(linearLayout); dialog.setCanceledOnTouchOutside(true); dialog.show(); setDialogSize(dialog); }

private void setDialogSize(Dialog dg) {


  Window dialogWindow = dg.getWindow();
  WindowManager.LayoutParams lp = dialogWindow.getAttributes();
  dialogWindow.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
  dialogWindow.setGravity(Gravity.RIGHT | Gravity.TOP);
  //显示的坐标
  lp.x = 150;
  lp.y = 50;
  dialogWindow.setAttributes(lp);
 }


R.Style.DialogStyle内容:

<style name="DialogStyle">  
        <item name="android:windowBackground">@android:color/transparent</item>  
        <item name="android:windowFrame">@null</item>  
        <item name="android:windowNoTitle">true</item>  
        <item name="android:windowIsFloating">true</item>  
        <item name="android:windowIsTranslucent">true</item>  
        <item name="android:windowContentOverlay">@null</item>  
        <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>  
        <item name="android:backgroundDimEnabled">true</item>  
</style>

  以上是完整的代码。
