android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="点击进入Layout1"
/>
< /LinearLayout>
最后是我们的核心程序setContentViewDemo.java
package com.android.setContentViewDemo;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class setContentViewDemo extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// 载入main.xml Layout
setContentView(R.layout.main);
// 以findViewById()取得Button对象并添加事件onClickLisener
Button bt1 = (Button) findViewById(R.id.bt1);
bt1.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
goToLayout2();
}
});
}
// 将layout由main.xml切换成mylayout.xml
public void goToLayout2() {
// 将layout改成mylayout
setContentView(R.layout.mylayout);
Button b2 = (Button) findViewById(R.id.bt2);
b2.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
goToLayout1();
}
});
}
// 将layout由mylayout.xml切换成main.xml
public void goToLayout1() {
setContentView(R.layout.main);
Button bt1 = (Button) findViewById(R.id.bt1);
bt1.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
goToLayout2();
}
});
}
}
最后执行之!,这一节就到此结束~
