如何做一个DialogActivity

setFinishOnTouchOutside(true);////////设置为true点击区域外消失

setContentView(R.layout.dialog_input_verify_code);

setToolbarVisiable(View.GONE);

finalLinearLayout iLayout_main = (LinearLayout)this.findViewById(R.id.dialog_input_verify_ll);

iLayout_main.getViewTreeObserver()

.addOnGlobalLayoutListener(newOnGlobalLayoutListener() {

@Override

public voidonGlobalLayout() {

intheight =iLayout_main.getMeasuredHeight();

WindowManager m = getWindowManager();

Display d = m.getDefaultDisplay();// 为获取屏幕宽、高

android.view.WindowManager.LayoutParams p = getWindow().getAttributes();

//                                              p.height = (int) (d.getHeight() * 0.5); // 高度设置为屏幕的0.8

p.height= height;

p.width= (int) (d.getWidth() *0.8);// 宽度设置为屏幕的0.7

getWindow().setAttributes(p);

}

});
