Android popupwindow 拦截返回键怎么弄的？

[qq_24697875]

popupWindow.setOutsideTouchable(false);
popupWindow.setFocusable(true);
contentView.setFocusable(true);
contentView.setFocusableInTouchMode(true);
contentView.setOnKeyListener(new View.OnKeyListener() {
@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
if (popupWindow != null) {
popupWindow.dismiss();
}
}
return false;
}
});
点击返回键不进OnKeyListener，怎么处理？

不是太明白，我也是个小白。如果LZ说的是让返回键失效的话，我这里有一个 @Override public boolean onKeyUp(int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_BACK) { return true; } return super.onKeyUp(keyCode, event); }

[MissZzz丶]

contentView.setOnKeyListener(new View.OnKeyListener() { @Override public boolean onKey(View v, int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_BACK) { if (popupWindow != null) { popupWindow.dismiss(); } return ture; //事件拦截，不要继续往下传了 } return false; } });

popupWindow = new PopupWindow(view,ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);用这个构造方法 然后在Activity的onKeyDown里拦截 @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_BACK) { if (popupWindow != null && popupWindow .isShowing()) { popupWindow.dismiss(); return true; } } return super.onKeyDown(keyCode, event); }
