java - android按钮onClick什么都不做

我正在尝试在自定义onClick上为Button实现Dialog功能，但是当我单击Button时没有任何反应。它是butEditAdd


  MainActivity.java：

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        final AddDialog addDialog = new AddDialog(MainActivity.this);
        addDialog.setContentView(R.layout.dialogedit);
        final Button butEditAdd =(Button)addDialog.findViewById(R.id.buttonAdd);
        //final Button butEditAdd=addDialog.getAdd();
        addDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
        butEditAdd.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //addDialog.dismiss();
                Toast.makeText(getApplicationContext(),"It's working",Toast.LENGTH_SHORT).show();
           }
        });
        addDialog.show();
    }
});

addDialog.java：

public class AddDialog extends Dialog implements android.view.View.OnClickListener{

Activity a;
Dialog d;
Button add , cancel;
RadioButton owes,lent ,money,things ;
EditText name ,amount,object,note;
Spinner spin;

public AddDialog(Activity c) {
    super(c);
    this.a = c;
}

@Override
public void onClick(View v){

};

@Override
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.dialogedit);
    add=(Button)findViewById(R.id.buttonAdd);
    cancel=(Button)findViewById(R.id.buttonCancel);
    owes = (RadioButton)findViewById(R.id.radioButtonOwes);
    lent = (RadioButton)findViewById(R.id.radioButtonLent);
    money = (RadioButton)findViewById(R.id.radioButtonAmount);
    things =(RadioButton)findViewById(R.id.radioButtonThings);
    name = (EditText)findViewById(R.id.editName);
    object = (EditText)findViewById(R.id.editTextWhat);
    amount =(EditText)findViewById(R.id.editTextAmount);
    note =(EditText)findViewById(R.id.editTextNote);
    spin=(Spinner) findViewById(R.id.spinnerdevise);

    owes.setOnClickListener(new  View.OnClickListener(){
        @Override
        public void onClick(View view) {
                lent.setChecked(false);
        }
    });
    lent.setOnClickListener(new  View.OnClickListener(){
        @Override
        public void onClick(View view) {
            owes.setChecked(false);
        }
    });
    money.setOnClickListener(new  View.OnClickListener(){
        @Override
        public void onClick(View view) {
            things.setChecked(false);
            object.setEnabled(false);
            amount.setEnabled(true);
            spin.setEnabled(true);
            object.setText("");

        }
    });
    things.setOnClickListener(new  View.OnClickListener(){
        @Override
        public void onClick(View view) {
            money.setChecked(false);
            object.setEnabled(true);
            amount.setEnabled(false);
            spin.setEnabled(false);
            amount.setText("");
        }
    });
    object.setOnClickListener(new  View.OnClickListener(){
        @Override
        public void onClick(View view) {
            things.performClick();
            things.setChecked(true);
        }
    });

    amount.setOnClickListener(new  View.OnClickListener(){
        @Override
        public void onClick(View view) {
            money.performClick();
            money.setChecked(true);

        }
    });

感谢帮助！

最佳答案

对话框片段具有不同的生命周期集。如果要创建类adddialog，则扩展对话框片段，然后在adddialog的oncreate中使用setcontent视图。

如果要创建简单的对话框，请尝试以下代码。这将解决您的问题。

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            final Dialog addDialog = new Dialog(this);
            addDialog.setContentView(R.layout.dialogedit);
            final Button butEditAdd =(Button)addDialog.findViewById(R.id.btn);
            //final Button butEditAdd=addDialog.getAdd();
            addDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
            butEditAdd.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    //addDialog.dismiss();
                    Toast.makeText(getApplicationContext(),"It's working", Toast.LENGTH_SHORT).show();
                }
            });
            addDialog.show();
        }
    });
