android PopupWindow点击EditText后返回键无法关闭。

大神们，快来看看这个神奇的问题吧！！
我在Activity弹出一个PopupWindow,PopupWindow上有一个EditText,如果我不去触碰它，我点击返回键可以把PopupWindow关闭，但是我一旦点了输入框，弹出软键盘，那这时我再怎么点返回键都没用，都关不了PopupWindow。以下是我的代码：

把contentview 那三行删掉 试试

问题应该出在这里：edittext获得焦点后弹出软键盘，软键盘的收起实际消费了返回键事件，而之后的分发都指向了软键盘，popupwindow无法截获该事件，具体如何改我还没有想好，稍后再跟帖。

好了，这个问题正如我上面说的那样，事件被分发到edittext了，为edittext 设置onKeyListener即可，可以参照一下以下代码。

public class PopUpWindowTestActivity extends Activity {

    private Button btnPopup;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_pop_up_window_test);

        btnPopup = (Button) findViewById(R.id.btn_popup);

        btnPopup.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                showPopupWindow(v);
            }
        });

    }

    private MPopupWindow popupWindow = null;

    protected void showPopupWindow(View v) {
        if (popupWindow == null)
            popupWindow = new MPopupWindow(this, 500, 300);
        popupWindow.show(v);
    }

    class MPopupWindow extends PopupWindow {

        private final Activity mContext;

        private View contentView;

        public MPopupWindow(Activity ctx, int width, int height) {
            super(width, height);
            this.mContext = ctx;

            contentView = LayoutInflater.from(mContext).inflate(
                    R.layout.popup_content, null);
            init();
        }

        private EditText txtTest;

        private void init() {
            txtTest = (EditText) contentView.findViewById(R.id.editText1);
            contentView.setFocusable(true);
            contentView.setFocusableInTouchMode(true);
            this.setFocusable(true);
            this.setOutsideTouchable(true);
            this.setContentView(contentView);
            this.setInputMethodMode(PopupWindow.INPUT_METHOD_FROM_FOCUSABLE);
            this.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);
            txtTest.setOnKeyListener(new OnKeyListener() {

                @Override
                public boolean onKey(View v, int keyCode, KeyEvent event) {
                    // TODO Auto-generated method stub
                    if (keyCode == KeyEvent.KEYCODE_BACK) {
                        dismiss();
                        return true;
                    }
                    return false;
                }
            });
        }



        public void show(View parent) {
            this.setBackgroundAplha(0.4f);
            this.showAtLocation(parent, Gravity.CENTER, 0, 0);
        }

        @Override
        public void dismiss() {
            setBackgroundAplha(1.0f);
            super.dismiss();
        }

        private void setBackgroundAplha(float alpha) {
            WindowManager.LayoutParams lp = mContext.getWindow()
                    .getAttributes();
            lp.alpha = alpha;
            mContext.getWindow().setAttributes(lp);
        }

    }

}

EditText获取焦点了，但是你惦记返回键是应该能关闭的

卤煮不要淘气，代码明明没问题。
public class PopwindowTest extends Activity {
Mu popupWindow;
View view;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    popupWindow = new Mu(this, 200, 100);
}

public void show(View v) {
    System.out.println("dianji");
    popupWindow.showAtLocation(v, Gravity.CENTER, 0, 0);
}

class Mu extends PopupWindow {
    Context context;

    public Mu(Context ctx, int width, int height) {
        super(width, height);
        this.context = ctx;
        view = LayoutInflater.from(context)
                .inflate(R.layout.pop_main, null);
        view.setFocusable(true);
        view.setFocusableInTouchMode(true);
        setContentView(view);
        view.setOnKeyListener(new OnKeyListener() {
            @Override
            public boolean onKey(View v, int keyCode, KeyEvent event) {
                // TODO Auto-generated method stub
                if (keyCode == KeyEvent.KEYCODE_BACK) {
                    popupWindow.dismiss();
                    return true;
                }
                return false;
            }
        });
        setFocusable(true);

        setInputMethodMode(PopupWindow.INPUT_METHOD_NEEDED);
        setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);
