android - 从 StringArray 创建按钮并设置 onClickListener

Question

我必须获取数组并使用它来动态创建 onClickListener()。我已经使用这种方法来创建动态按钮。有人知道如何使用数组动态创建 onClickListener() 吗？

for (int i = 0; i < categoryName.size(); i++) {

    Button btn = new Button(this);
    btn.setId(Integer.parseInt(categoryID.get(i).toString()));
    btn.setHint(categoryID.get(i).toString());
    btn.setText(categoryName.get(i)); //another array with the name of the IDS
    btn.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            //example
            Toast.makeText(getApplicationContext(),categoryID.get(i),Toast.LENGTH_LONG).show();
        }
    });
    buttonLayout.addView(btn, new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
}

Answer 1

只放 btn.setOnClicklistener(this); 而不是

btn.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        //example
        Toast.makeText(getApplicationContext(),categoryID.get(i),Toast.LENGTH_LONG).show();
    }
}); 

点击():

@Override
public void onClick(View v) {
    //example
    //you can check its view 
    //here V gives you BtnId 
}
