评级栏未显示在警报对话框中

Question

我正在创建一个应用程序，我允许客户对应用程序进行评分。

我有两个问题

首先。

我在警报对话框中添加了评级栏，但不知道为什么它会覆盖我为提交评级而创建的按钮。 我已经尝试使用 margin-top for button 仍然无法正常工作

第二。

提交时也没有显示吐司消息。

警报对话框代码

if (id == R.id.nav_rate) {
        AlertDialog.Builder mBuild = new AlertDialog.Builder(homeActivity.this);
        View mView = getLayoutInflater().inflate(R.layout.ratingbar,null);
        final RatingBar ratebar = (RatingBar)mView.findViewById(R.id.ratingBar);
        Button btnSubmit=(Button)mView.findViewById(R.id.btnSubRating);
        btnSubmit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
            ratebar.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
                @Override
                public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {
                    Toast.makeText(homeActivity.this, ((int) rating),Toast.LENGTH_LONG).show();
                }
            });
            }
        });
        mBuild.setView(mView);
        AlertDialog dialog=mBuild.create();
        dialog.show();
    }

public class homeActivity extends AppCompatActivity  {


    private float rateValue;

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


            AlertDialog.Builder mBuild = new AlertDialog.Builder(homeActivity.this);
            View mView = getLayoutInflater().inflate(R.layout.ratingbar,null);

            final RatingBar ratebar = (RatingBar)mView.findViewById(R.id.ratingBar);
            ratebar.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
                @Override
                public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {
                    rateValue = rating;
                    Toast.makeText(homeActivity.this, ""+rating, Toast.LENGTH_SHORT).show();
                }

Answer 2

您已经修复了对话框的大小，该大小不允许评分栏放入其中。

替换dialog.getWindow().setLayout(600, 400);

与dialog.getWindow().setLayout(800, 600);

在您的活动中

创建类变量：-

 float rating=0;

并使用它来存储评级点击评级

    AlertDialog.Builder mBuild = new AlertDialog.Builder(MainActivity.this);
    View mView = getLayoutInflater().inflate(R.layout.ratingbar,null);
    final RatingBar ratebar = (RatingBar)mView.findViewById(R.id.ratingBar);
    Button btnSubmit=(Button)mView.findViewById(R.id.btnSubRating);

ratebar.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
    @Override
    public void onRatingChanged(RatingBar ratingBar, float v, boolean b) {
        rating=v;
    }
});
    btnSubmit.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Toast.makeText(homeActivity.this, String.valueOf(ratebar.getRating()),Toast.LENGTH_LONG).show();
        }
    });
    mBuild.setView(mView);
    AlertDialog dialog=mBuild.create();
    dialog.getWindow().setLayout(600, 400);
    dialog.show();
}

Answer 3

试试吧：

AlertDialog alertDialog = mBuild.show();

反而：

AlertDialog dialog=mBuild.create();
dialog.getWindow().setLayout(600, 400);
dialog.show();

此外： android:layout_above 只允许在 RelativeLayout 上（所以删除它）
