android开发中通过View的getDrawingCache方法可以达到截屏的目的，只是缺少状态栏！
原始界面
截屏得到的图片
代码实现
1. 添加权限(AndroidManifest.xml文件里)
2. 添加1个Button(activity_main.xml文件)
xmlns:tools="/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:text="@string/hello_world" />
android:id="@+id/btn_save"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Screenshot"
/>
3. 实现截屏(MainActivity.java文件)
package com.example.androidtest;
import java.io.File;
import java.io.FileOutputStream;
import android.os.Bundle;
import android.os.Environment;
import android.app.Activity;
import android.graphics.Bitmap;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn = (Button) this.findViewById(R.id.btn_save);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
screenshot();
}
});
}
private void screenshot()
{
// 获取屏幕
View dView = getWindow().getDecorView();
dView.setDrawingCacheEnabled(true);
dView.buildDrawingCache();
Bitmap bmp = dView.getDrawingCache();
if (bmp != null)
{
try {
// 获取内置SD卡路径
String sdCardPath = Environment.getExternalStorageDirectory().getPath();
// 图片文件路径
String filePath = sdCardPath + File.separator + "screenshot.png";
File file = new File(filePath);
FileOutputStream os = new FileOutputStream(file);
press(pressFormat.PNG, 100, os);
os.flush();
os.close();
} catch (Exception e) {
}
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
