Android动态添加EditText

Question

在单击按钮时，我想动态地创建EDITTEXT并垂直显示它们。我有这个代码，但它只创建一个EditText。我哪里错了?谢谢你的帮助。

private LinearLayout containerLayout;
static int totalEditTexts = 0;
private Button button;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.add_category);
    containerLayout = (LinearLayout)findViewById(R.id.relative1);
    button = (Button)findViewById(R.id.button);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
            totalEditTexts++;
            EditText editText = new EditText(getBaseContext());
            containerLayout.addView(editText);
            editText.setGravity(Gravity.LEFT);
            LinearLayout.LayoutParams layoutParams = (LinearLayout.LayoutParams) editText.getLayoutParams();
            layoutParams.width = LinearLayout.LayoutParams.MATCH_PARENT;
            layoutParams.setMargins(23, 34, 0, 0);
            editText.setLayoutParams(layoutParams);
            editText.setTag("EditText" + totalEditTexts);
        }
    });

}

你的例子工作完美，如果你的add_category.xml看起来像这样:https://gist.github.com/akodiakson/9d37e3e48d0798d106c3

所以我猜你的Activity布局可能有点偏离。
