Android按钮Onclick [英] Android Button Onclick

问题描述

好的我是android dev和Java的新手，所以我在点击方法上遇到问题这里是我的代码。我知道我必须要亲近，提前谢谢。我希望我的按钮所做的就是，当它点击手机将布局视图从main.xml切换到xx.xml时

OK I'm new to android dev's and Java, so I'm having problems with on click method here's my code. I know I've gotta be close, thanks in advance. All I want my button to do is, when its clicked on the phone to switch the layout view from main.xml to xx.xml

package my.project;

import android.app.Activity;
import android.os.Bundle;

import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class ExperiencerlActivity extends Activity {
    /** Called when the activ`enter code here`ity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);      
        Button button = (Button) findViewById(R.id.button1);

        button.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                // TODO Auto-generated method stub
            }
        });
    }
}

这是我的按钮代码

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_above="@+id/linearLayout1"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="56dp"
    android:onClick="setLogin"
    android:text="Login" />

推荐答案

如果写得像这在xml文件的Button标签中： android：onClick =setLogin然后

这样做：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<Button
    android:id="@+id/button1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/btn"
    android:onClick="onClickBtn" />

</LinearLayout>

和代码部分：

public class StartUpActivity extends Activity 
{
    public void onCreate(Bundle savedInstanceState) 
    {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);    
    }

    public void onClickBtn(View v)
    {
        Toast.makeText(this, "Clicked on Button", Toast.LENGTH_LONG).show();
    } 
}

并且不需要所有这些：

 Button button = (Button) findViewById(R.id.button1);
 button.setOnClickListener(new OnClickListener() {

    public void onClick(View v) {
        // TODO Auto-generated method stub

    }
 });

检查一次;
