如何使用触摸侦听器停用布局的alpha“颜色”

标签: java android xml popup popupwindow

您好我创建了一个测验应用程序,第二个java类(Menu2)上有一个Button,如果有人点击此按钮,会出现一个弹出窗口,背景(Menu2的布局)获得0.1的alpha /透明度。当有人点击在POPUPWINDOW 时,弹出窗口将自行关闭,透明度将设置为 1 。但如果somene在弹出窗口外点击,弹出窗口会关闭,但透明度会持续......我该如何解决?

MENU2:

        public class Menu2 extends AppCompatActivity {




private DrawerLayout mDrawerLayout2;
private ActionBarDrawerToggle mToggle;
private Toolbar mToolbar;
private Button popup;
private PopupWindow popupWindow;private LayoutInflater layoutInflater; //Alows to add a new layout in our window



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_menu2);


     TextView txtScore = (TextView) findViewById(R.id.textScore2);
     TextView txtHighScore = (TextView)findViewById(R.id.textHighScore);
     ImageView imgTrophyView1 = (ImageView)findViewById(R.id.trophy1);
     ImageView imgTrophyView2 = (ImageView) findViewById(R.id.trophy2);
     TextView trophy1Txt = (TextView) findViewById(R.id.trophy1Text);
     TextView trophy2Txt = (TextView) findViewById(R.id.trophy2Text);

    Intent intent = getIntent();
    int mScore = intent.getIntExtra ("score",0);
    txtScore.setText("Your score is: " + mScore);

    SharedPreferences sharedpreferences = getSharedPreferences("mypref", Context.MODE_PRIVATE);
    int applyView =sharedpreferences.getInt("currentscore",0);


    SharedPreferences mypref =getPreferences(MODE_PRIVATE);
    int highScore = mypref.getInt("highScore", 0);
    if (highScore>= mScore)
        txtHighScore.setText("High score: " + highScore);


    else{
        txtHighScore.setText("New highscore: " + mScore);

        SharedPreferences.Editor editor = mypref.edit();
        editor.putInt("highScore",mScore);
        editor.commit();

    }

    if (applyView >=10) {
        imgTrophyView1.setVisibility(View.VISIBLE);
        trophy1Txt.setVisibility(View.VISIBLE);
    }
        if (applyView >= 20){
            imgTrophyView2.setVisibility(View.VISIBLE);
            trophy2Txt.setVisibility(View.VISIBLE);
    }


    popup = (Button)findViewById(R.id.enablePOPUP);
    popup.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            layoutInflater =(LayoutInflater) getApplicationContext().getSystemService(LAYOUT_INFLATER_SERVICE);
            ViewGroup container = (ViewGroup)layoutInflater.inflate(R.layout.popup_menu2_1,null);
            popupWindow = new PopupWindow(container,1000,980,true); //400,400=popUp size, true = makes that we can close the pop up by simply click out of the window
            popupWindow.showAtLocation(mDrawerLayout2, Gravity.CENTER, 0, 0);
            mDrawerLayout2.setAlpha((float) 0.1);

            container.setOnTouchListener(new View.OnTouchListener(){

                @Override

                        public boolean onTouch(View view, MotionEvent motionEvent  ){
                        mDrawerLayout2.setAlpha((float) 1);
                              popupWindow.dismiss();

                        return true;

                }
            });
        }
    });





    mToolbar = (Toolbar)findViewById(R.id.nav_action);
    setSupportActionBar(mToolbar);
    mDrawerLayout2 = (DrawerLayout) findViewById(R.id.drawerLayout2);

    mToggle = new ActionBarDrawerToggle(this, mDrawerLayout2, R.string.open, R.string.close);
    mDrawerLayout2.addDrawerListener(mToggle);
    mToggle.syncState();
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    NavigationView mNavigationView = (NavigationView) findViewById(nv2);
    mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {

        @Override
        public boolean onNavigationItemSelected(MenuItem menuItem){
            switch (menuItem.getItemId()){
                case(R.id.nav_home2):
                    Intent accountActivity2 = new Intent(getApplicationContext(),QuizActivity.class);
                    startActivity(accountActivity2);

            }
            return true;
        }
    });}

            public void onClick(View view) {

                Intent intent = new Intent(Menu2.this, QuizActivity.class);
                startActivity(intent);

}




@Override //Makes that the "Burger" Item, shows the Drawer if someone clicks on the simbol
public boolean onOptionsItemSelected(MenuItem item) {
    if (mToggle.onOptionsItemSelected(item)) {
        return true;
    }
    return super.onOptionsItemSelected(item);


}

}

尝试这样做:

popupWindow.setOnDismissListener(new PopupWindow.OnDismissListener() {

    @Override
    public void onDismiss() {
        mDrawerLayout2.setAlpha((float) 1);
        popup.dismiss();

    }
});
