Dismiss activity in android
提问by indira
I am using the following code to show “Hello” message with ok button when the user clicks a button. In some applications this is working fine. ie while clicking the ok button, the activity is dismissed. But in one application, this is not getting dismissed after clicking the ok button. What to do? Please help.
我使用以下代码在用户单击按钮时显示带有确定按钮的“Hello”消息。在某些应用程序中，这工作正常。即在单击确定按钮时，活动被解除。但在一个应用程序中，单击“确定”按钮后不会取消此操作。该怎么办？请帮忙。
public class MyClass extends Activity {
private TextView labelTxt;
private Button okBtn;
@Override
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.message);
labelTxt = (TextView) findViewById(R.id.txt);
labelTxt.setText("Hello");
okBtn = (Button) findViewById(R.id.okBtn);
okBtn.setOnClickListener(okBtnClickListener);
}
private final OnClickListener okBtnClickListener = new OnClickListener() {
public void onClick(View v) {
finish();
}
};
}
