的onClick不工作在OnCreate中 [英] onClick not working In OnCreate

问题描述

所以我有一个2个按钮的布局

So I have a 2 buttons in a layout

像这样：

    <LinearLayout android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:onClick="onClick">

<Button
    android:id="@+id/btnEdit"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:text="Edit Spot" />
<Button android:id="@+id/btnGo" 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="Google Spot"
    android:layout_weight="1"/>     
</LinearLayout>

然后在OnCreate为这个活动我有：

Then in the onCreate for the activity for this I have:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.view_spot);

    // save button
    ButtonEdit = (Button)findViewById(R.id.btnEdit);
    ButtonGo = (Button) findViewById(R.id.btnGo);

    // getting product details from intent
    Intent i = getIntent();

    // getting product id (pid) from intent
    pid = i.getStringExtra(TAG_PID);

    // Getting complete product details in background thread
    new GetProductDetails().execute();

    // save button click event
    ButtonEdit.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {
            Toast.makeText(getApplicationContext(), "Edit button pressed", Toast.LENGTH_LONG).show(); 
        }
    });

    // Go button click event
    ButtonGo.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {
            Toast.makeText(getApplicationContext(), "Go button pressed!", Toast.LENGTH_LONG).show();
        }
    });
}

但由于某些原因，当我点击的按钮没有任何反应。我在别人问这个问题左顾右盼，试图这些，但仍然一无所获。是否有人可以帮助我弄清楚为什么它不工作？

But for some reason when I tap the buttons nothing happens. I've looked around at others asking the question and tried those but still nothing. Can someone please help me figure out why it isn't working?

推荐答案

您必须在添加的onClick 属性按钮的定义，而不是在的LinearLayout 。

即使你想重用名为的onClick 您可以设置每个按键的标记，并做了开关为每个标签。例如：

Even if you want to reuse the same method called onClick you can set a tag for each button, and do a switch for each tag. For instance:

在您的布局：

android:tag="1"

在您的code：

public void onClick(View v) {
  String tag = (String) v.getTag();

  switch (Integer.parseInt(tag)) {
    case 1:  // First button
      ... 
      break;

    case 2:  // Second button
      ...
      break;
  }
}
