ListView的OnItemClick不起作用

Question

I made a listview. Using this tutorial link It works fine. But the problem is when i try to add onitemclick listener in its activity class the click action does not work.i just want to show a toast message.And here it the code for onItemClickListener

listViewCity.setOnItemClickListener(new OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> a, View v, int position, long id) { 

                    String item = ((TextView)v).getText().toString();

                    Toast.makeText(getApplicationContext(), item, Toast.LENGTH_LONG).show();

            }  
        });

Why it doesn't work anybody can tell me???

Answer 1

If you are getting an exception or a force close, you should have mentioned it.

First of all, your OnItemClickListener is wrong, because the View that is passed to your OnClickListener is not a TextView so You can not just cast it to a TextView.

You can fix it using the following:

listViewCity.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> a, View v, int position, long id) { 
        String item = ((TextView)v.findViewById(R.id.cityName)).getText().toString();
            Toast.makeText(getApplicationContext(), item, Toast.LENGTH_LONG).show();

    }  
});

Try what I just did and it should work. If it doesn't work, you may need to remove the line android:autoLink="web" from your xml file.

The attribute android:autoLink="web" is making your View's TextView Clickable. As I mentioned in my comment, if any of your subviews is clickable, your OnItemClickListener will not receive events, because it will be consumed by the children.

Use this

Since you are using a customadapter you will have to do this in your customadapter class to handle onclicks of the listview...

convertView.setClickable(true);
    convertView.setOnClickListener(new OnClickListener() {

                    @Override
                    public void onClick(View paramView)
                    {
                      //if you want you can use the "position" value to get the desired row items.
                    }
                    });

Try this...

listViewCity.setOnItemClickListener(new OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> a, View v, int position, long id) { 
                     String item = listViewCity.getItemAtPosition(position).toString();

                    Toast.makeText(getApplicationContext(), item, Toast.LENGTH_LONG).show();

            }  
        });

I had the same problem and solved it by setting each view I needed to click to clickable and then added the listener. I put the following method inside the customized adapter (in getView method). Something like this:

public void setViewsClickable(int position) {
        myView.button.setClickable(true);
        myView.radioButton.setClickable(true);
        myView.button.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // what this button should do
            }
        });

        myView.radioButton.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // what clicking this radio button should do
            }
        });

    }
