android |对话框中的多个onclicklistener

更新时间:2023-01-24 13:24:20

使您的活动实现 OnClickListener ,然后处理 onClick 事件,如下所示:

  @Override 
public void onClick(View v){
switch(v.getId()){
case R.id.img1:
...
休息
case R.id.img2:
...
break;
}
}


Inside my Activity I start a simple dialog.

final Dialog myDialog = new Dialog(this);
myDialog.setContentView(R.layout.testing);
...

My testing.xml Layout consists of nothing but 10 ImageViews, id`s are '1' to '10'.

I want every ImageView to be clickable and to do something. The define the onclick() methode in the .xml file isn`t working, as the methode can't be found when the dialog is viewed.

The only way I got it work is following: define 10 onclick-listeners:

ImageView img_1 = (ImageView) myDialog.findViewById(R.id.1);
ImageView img_2 = (ImageView) myDialog.findViewById(R.id.2);
...

img_1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
  execute_funtion(1);
  myDialog.cancel();
}
});

img_2.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
  execute_funtion(2);
  myDialog.cancel();
}
});

...

However, that's really bad code, I have 10 times nearly the same lines.

So my question: How can I make that work with clean code? I thought about a multiple onclicklistener (overwride the onClick() function and make a switch/case in the functions or something like that), but it's not working.

I'm happy about every idea! Thanks

/EDIT

Here a snippet of the .xml file

<ImageView
  android:id="@+id/1"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:padding="2dp"
  android:onClick="myFunction"
  android:src="@drawable/ic_launcher" />

Make your Activity implement OnClickListener and then process the onClick event like below:

@Override
public void onClick(View v) {
    switch (v.getId()) {
    case R.id.img1:
        ...
        break;
    case R.id.img2:
        ...
        break;
    }
}
