Android Inflater/查看异常

Question

我正在尝试向 Profile.java 中的自定义 AlertDialog 添加布局（profile_upload） 第一次它工作正常。但是当我关闭 AlertDialog 并再次单击按钮时它会崩溃 sayng java.lang.IllegalStateException：指定的孩子已经有一个父母。您必须先在孩子的父母上调用 removeView() Profile.java

Answer 1

alertDialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
            @Override
            public void onCancel(DialogInterface dialog) {



            }
        });

删除这里的所有视图，当你按下导航返回按钮时它会调用

Answer 2

或者，您可以通过 AlertDialog.Builder.create() 而不是 AlertDialog.Builder 实例来保留 AlertDialog 实例。
如果您使用自定义视图，则会创建对话框，然后每次 AlertDialog.Builder.show() 都会将自定义视图附加到对话框窗口。

public class Profile extends AppCompatActivity implements View.OnClickListener {
    AlertDialog dialog;
    ImageButton profile_btn;
    TextView tx_img_name;
    Button btn_prfil_upld, btn_pic_choose;
    ImageView img_prfl;
    View v;
    LayoutInflater inflater;

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

        profile_btn = (ImageButton) findViewById(R.id.user_profile_photo);
        profile_btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if(dialog == null) {
                    dialog = getBuilder().create();
                }
                dialog.setTitle("Update Profile Picture");
                dialog.show();

            }
        });
    }

    @NonNull
    private AlertDialog.Builder getBuilder() {
        AlertDialog.Builder alert = new AlertDialog.Builder(this);
        inflater = Profile.this.getLayoutInflater();
        if (v == null) {
            v = inflater.inflate(R.layout.profile_upload, null, false);
        } else {
            ((ViewGroup) v.getParent()).removeView(v);
        }
        alert.setView(v);


        btn_prfil_upld = (Button) v.findViewById(R.id.btnUpload_profile_pic);
        btn_pic_choose = (Button) v.findViewById(R.id.btn_choose_profile_pic);
        img_prfl = (ImageView) v.findViewById(R.id.img_profile_upload);
        tx_img_name = (TextView) v.findViewById(R.id.tx_img_name);
        btn_prfil_upld.setOnClickListener(this);
        btn_pic_choose.setOnClickListener(this);
        return alert;
    }

    public void onClick(View view) {
        int id = view.getId();
        switch (id) {
            case R.id.btn_choose_profile_pic:
                break;
            case R.id.btnUpload_profile_pic:
                break;
        }
    }
}
