Question

我的班级Android extends Dialog

public class DialogSearch extends Dialog{

    public ImageButton imageButtonCancel ;


    public DialogSearch(Context context, int theme) {
        super(context, theme);
        setContentView(R.layout.finddialog);

        imageButtonCancel = (ImageButton) findViewById(R.id.imageButtonFindCancel);
        imageButtonCancel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //hide();
                dismiss();
            }
        });

        this.show();
    }
}

这不是我的ActivityClass，我可以从ActivityClass进行实例化，但是当我点击imageButtonCancel关闭时，我无效。我尝试了hide()和close()两种方法。

这是我的R.Layout.finddialog

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="wrap_content" android:layout_height="wrap_content"
>

<AutoCompleteTextView
    android:id="@+id/editTextFind"
    android:layout_width="200dp"
    android:layout_height="wrap_content"
    android:text="write here"
    android:textSize="18sp"
    android:layout_alignParentTop="true"
    android:layout_alignParentLeft="true" />

<ImageButton
    android:id="@+id/imageButtonFindSearch"
        android:layout_toRightOf="@+id/editTextFind"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/find_icone"
        android:layout_marginRight="10px"
     />   

<ImageButton
    android:id="@+id/imageButtonFindCancel"
        android:layout_below="@+id/radioGroupeFind"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/cancel_icone"
        android:layout_alignRight="@+id/imageButtonFindSearch"

     />   


</RelativeLayout>

我是从ActivityClass

调用的

public class mapActivity extends Activity {


    private ImageButton buttonSearch ;


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // full screen
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);

        setContentView(R.layout.main);
        buttonSearch = (ImageButton) findViewById(R.id.buttonSearchMain) ;   

         buttonSearch.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                 dialogSearch = new DialogSearch(mapActivity.this,R.style.FullHeightDialog); // this for not display dialog title part
            }
        });

    }
}

感谢。

Answer 1

尝试DialogSearch.this.dismiss();

Answer 2

试试这个...使用onCreate（）方法......

public class DialogSearch extends Dialog {
    public DialogSearch(Context context) {
        super(context);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // hides title bar...
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.finddialog);

        ImageButton imageButtonCancel = (ImageButton) findViewById(R.id.imageButtonFindCancel);
        imageButtonCancel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // hide();
                dismiss();
            }
        });
    }
}

无法关闭我的Dialog
