定义，在这两种资源的文件出现在你的代码 并在onCreate()在所有视图中Activity可以检查方向绑定的意见，你的类的对象。
示例。
在这里我们有包含在这两个文件的ImageView的，并在画像文件有一个TextView和景观它包含Button代替TextView
my_layout.xml在布局2个布局文件-land
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/abs__ab_bottom_solid_dark_holo" />
my_layout.xml在布局端口文件夹
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/abs__ab_bottom_solid_dark_holo" />
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />
这里是活动代码
package com.example.stackoverflow;
import android.app.Activity;
import android.content.res.Configuration;
import android.os.Bundle;
import android.view.Display;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;
public class MyActivity extends Activity {
// landscape views
Button button1;
// protrati views
TextView textView1;
// common views (shared between landscape and protrait mode)
ImageView imageView1;
public MyActivity() {
// TODO Auto-generated constructor stub
}
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.my_layout);
imageView1 =(ImageView) findViewById(R.id.imageView1);//exist inside landscape file and portrait
if(getScreenOrientation() == Configuration.ORIENTATION_PORTRAIT){
textView1 = (TextView)findViewById(R.id.textView1);
}else{
button1 = (Button) findViewById(R.id.button1);
}
//when you want to access any thing that is not shared
//check the orientation
}
@Override
protected void onResume() {
super.onResume();
//let say that we want here to set a text on the textview and it's available only for protrait
if(getScreenOrientation() == Configuration.ORIENTATION_PORTRAIT){
//won't be null :) so we can set the text
textView1.setText("Hello Guys!");
}
}
// http://stackoverflow.com/a/6236110/671676
public int getScreenOrientation() {
Display getOrient = getWindowManager().getDefaultDisplay();
int orientation = Configuration.ORIENTATION_UNDEFINED;
if (getOrient.getWidth() == getOrient.getHeight()) {
orientation = Configuration.ORIENTATION_SQUARE;
} else {
if (getOrient.getWidth() < getOrient.getHeight()) {
orientation = Configuration.ORIENTATION_PORTRAIT;
} else {
orientation = Configuration.ORIENTATION_LANDSCAPE;
}
}
return orientation;
}
}
问什么，你不明白。
