问题描述
我试图用确认对话框回去,这样我决定来处理onback pressed(),然后我已经把我的code代表与空监听确定和取消按钮确认对话框。
结果
@覆盖
公共无效onBack pressed(){
AlertDialog.Builder建设者=新AlertDialog.Builder(本);
builder.setTitle(确认书);
builder.setMessage(你确定要退出吗?);
builder.setPositiveButton(OK,NULL);
builder.setNegativeButton(取消,NULL);
builder.show();
}
结果它工作得很好,但如果我点击确定,但应该继续()pssed super.onback $ P $,否则就应该在同一活动的行为问题。
结果
以下code,我曾试图。
结果
@覆盖
公共无效onBack pressed(){
AlertDialog.Builder建设者=新AlertDialog.Builder(本);
builder.setTitle(确认书);
builder.setMessage(你确定要退出吗?);
builder.setPositiveButton(OK,新DialogInterface.OnClickListener(){ @覆盖
公共无效的onClick(DialogInterface对话,诠释它){
//super.onBack$p$pssed();
}
});
builder.setNegativeButton(取消,NULL);
builder.show();
}
把this.finish()来完成您的活动正按钮的onclick ...
builder.setPositiveButton(OK,新DialogInterface.OnClickListener(){ @覆盖
公共无效的onClick(DialogInterface对话,诠释它){
//super.onBack$p$pssed();
this.finish();
}
});
I was tried to go back with confirmation dialog so that i was decided to handle onbackpressed() and then i had put my code for confirm dialog with ok and cancel button for null listener.
@Override
public void onBackPressed() {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Confirmation");
builder.setMessage("Are you sure want to exit?");
builder.setPositiveButton("OK",null);
builder.setNegativeButton("Cancel", null);
builder.show();
}
It was worked fine but the problem is if i click ok but it should continue for behaviour of super.onbackpressed() otherwise it should be in same activity.
the following code that i had tried.
@Override
public void onBackPressed() {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Confirmation");
builder.setMessage("Are you sure want to exit?");
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
//super.onBackPressed();
}
});
builder.setNegativeButton("Cancel", null);
builder.show();
}
put this.finish() to finish your activity in onclick of positive button ...
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
//super.onBackPressed();
this.finish();
}
});
