当点击一个按钮时，它会转到相应的页面。实现这个的最好/最简单的方法是什么？当我尝试 onclick 监听器时，我尝试了所有方法均无效。我可以让一名听众工作，但当我尝试让多名听众工作时，它就会变得困惑，我无法弄清楚。
我当前的方法是使用这2个java文件
Activity 1.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.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
activity2.java
包安装.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);
}}
最佳答案
您应该为每个页面定义一项 Activity 。包括主要 Activity 在内，总共有 7 个 Activity 。在主 Activity 中，定义单个 onClickListener 来处理所有点击。
class ClickListener implements View.OnClickListener {
void onClick(View v) {
switch(v.getId()) {
case R.id.btn_1:
...
break;
...
}
}
将此监听器设置为所有 6 个按钮。
