带有 onclick 侦听器的 Android 按钮导航 [英] Android button navigation with onclick listeners
问题描述
main.xml
--------
|button1| (button press)>page1.xml
|button2| (button press)>page2.xml
|button3| (button press)>page3.xml
|button4| (button press)>page4.xml
|button5| (button press)>page5.xml
|button6| (button press)>page6.xml
-------------------------------------------
当一个按钮被点击时，它会转到相应的页面.实现这一点的最佳/最简单的方法是什么?当我尝试 onclick 监听器时，我已经尝试了一切都无济于事.我可以让一个听众工作，但是当我尝试让一个以上的听众工作时，它就搞砸了，我无法弄清楚.我目前的方法是使用这两个 java 文件
活动1.java
When a button is clicked it goes to a corresponding page. What is the best/easiest way to implement this? I have tried everything to no avail when I try onclick listeners. I can get one listener to work but when I try to get more than one it messes up and I can't figure it out.
My current method is using these 2 java files
activity1.java
package install.fineline;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.widget.Button;
import android.view.View;
import android.view.View.OnClickListener;
public class Activity1 extends Activity {
Button Button1;
Button Button2;
Button Button3;
Button Button4;
Button Button5;
Button Button6;
public void addListenerOnButton() {
final Context context = this;
Button1 = (Button) findViewById(R.id.autobody);
Button1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Intent intent = new Intent(context, Activity2.class);
startActivity(intent);
}
});
Button2 = (Button) findViewById(R.id.glass);
Button2.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Intent intent = new Intent(context, Activity2.class);
startActivity(intent);
}
});
Button3 = (Button) findViewById(R.id.wheels);
Button3.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Intent intent = new Intent(context, Activity2.class);
startActivity(intent);
}
});
Button4 = (Button) findViewById(R.id.speedy);
Button4.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Intent intent = new Intent(context, Activity2.class);
startActivity(intent);
}
});
Button5 = (Button) findViewById(R.id.sevan);
Button5.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Intent intent = new Intent(context, Activity2.class);
startActivity(intent);
}
});
Button6 = (Button) findViewById(R.id.towing);
Button6 = (Button) findViewById(R.id.towing);
Button6.setOnClickListener(new OnClickListener() {
Button6.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Intent intent = new Intent(context, Activity2.class);
startActivity(intent);
}
});
}}
这是我的另一个 java 文件
and here is my other java file
activity2.java
包 install.fineline;
activity2.java
package install.fineline;
import android.app.Activity;
import android.os.Bundle;
import android.widget.Button;
public class Activity2 extends Activity {
Button button1;
public void onCreate1(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.autobody);
}
Button button2;
public void onCreate2(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.glass);
}
Button button3;
public void onCreate3(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.wheels);
}
Button button4;
public void onCreate4(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.speedy);
}
Button button5;
public void onCreate5(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.sevan);
}
Button button6;
public void onCreate6(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.towing);
}}
推荐答案
您应该为每个页面定义一个活动.所以总共有7个活动，包括主要的.在主活动中，定义单个 onClickListener 来处理所有点击.
You should define one activity for each of the pages. So totally 7 activities including the main. In main activity, define single onClickListener to handle all clicks.
class ClickListener implements View.OnClickListener {
void onClick(View v) {
switch(v.getId()) {
case R.id.btn_1:
...
break;
...
}
}
将此侦听器设置为所有 6 个按钮.
Set this listener to all your 6 buttons.
