mInstance.setOutsideTouchable(false);
mInstance.setFocusable(false); 2、activity调用代码
1下拉式弹出
private CommonPopupWindow.LayoutGravity layoutGravity;private CommonPopupWindow window;private View activityPopup;
activityPopupfindViewById(R.id.activity_popup); textView.setOnClickListener(new View.OnClickListener() {Overridepublic void onClick(View view) {PopupWindow winwindow.getPopupWindow();win.setAnimationStyle(R.style.animTranslate);//动画效果window.showBashOfAnchor(textView, layoutGravity, 0, 0);//跟随式弹出
// window.showAtLocation(activityPopup, Gravity.BOTTOM, 0, 0);//底部弹出WindowManager.LayoutParams lpgetWindow().getAttributes();lp.alpha0.3f;getWindow().addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);getWindow().setAttributes(lp);}});
下拉式实例化
private void initPopup2(){layoutGravitynew CommonPopupWindow.LayoutGravity(CommonPopupWindow.LayoutGravity.CENTER_HORI| CommonPopupWindow.LayoutGravity.TO_BOTTOM);DisplayMetrics dm new DisplayMetrics();getWindowManager().getDefaultDisplay().getMetrics(dm);int nMultiple dm.widthPixels;//宽windownew CommonPopupWindow(this, R.layout.mypopup, (int) (nMultiple*0.4), ViewGroup.LayoutParams.WRAP_CONTENT) {Overrideprotected void initView() {View viewgetContentView();linearLayout (LinearLayout)view.findViewById(R.id.oneli);}Overrideprotected void initEvent() {linearLayout.setOnClickListener(new View.OnClickListener() {Overridepublic void onClick(View view) {Toast.makeText(MainActivity.this,ssssblue,Toast.LENGTH_SHORT).show();}});}Overrideprotected void initWindow() {super.initWindow();PopupWindow instancegetPopupWindow();instance.setOnDismissListener(new PopupWindow.OnDismissListener() {Overridepublic void onDismiss() {WindowManager.LayoutParams lpgetWindow().getAttributes();lp.alpha1.0f;getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);getWindow().setAttributes(lp);}});}};
}
2底部弹出 private void initPopupWindow() {DisplayMetrics dm new DisplayMetrics();getWindowManager().getDefaultDisplay().getMetrics(dm);int nMultiple dm.widthPixels;//宽// windownew CommonPopupWindow(this, R.layout.mypopup, ViewGroup.LayoutParams.MATCH_PARENT, (int) (screenHeight*0.7)) {windownew CommonPopupWindow(this, R.layout.mypopup, (int) (nMultiple*0.9), ViewGroup.LayoutParams.WRAP_CONTENT) {Overrideprotected void initView() {View viewgetContentView();linearLayout (LinearLayout)view.findViewById(R.id.oneli);}Overrideprotected void initEvent() {linearLayout.setOnClickListener(new View.OnClickListener() {Overridepublic void onClick(View view) {Toast.makeText(MainActivity.this,ssssblue,Toast.LENGTH_SHORT).show();}});}Overrideprotected void initWindow() {super.initWindow();PopupWindow instancegetPopupWindow();instance.setOnDismissListener(new PopupWindow.OnDismissListener() {Overridepublic void onDismiss() {WindowManager.LayoutParams lpgetWindow().getAttributes();lp.alpha1.0f;getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);getWindow().setAttributes(lp);}});}};} window.getPopupWindow().dismiss();//隐藏 demo链接PopupWindow实现demo-Android代码类资源-CSDN下载 下拉式弹出窗 全屏底部弹出窗
