试试这个code,不要忘了添加此权限在你的Manifest.xml
Try this code, don't forget to add this permission in your Manifest.xml
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
的main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/screen"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello" />
<Button
android:id="@+id/capturescreen"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Capture Screen" />
<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:background="@drawable/roundcorner"
android:scaleType="fitXY"

ImageView bmImage;
Button btnScreenDialog_OK;

screen = (View) findViewById(R.id.screen);
Button btnCaptureScreen = (Button) findViewById(R.id.capturescreen);
btnCaptureScreen.setOnClickListener(new OnClickListener() {

File saved_image_file = new File(
Environment.getExternalStorageDirectory()

if (saved_image_file.exists())
saved_image_file.delete();
try {
FileOutputStream out = new FileOutputStream(saved_image_file);
bmScreen2.compress(Bitmap.CompressFormat.PNG, 100, out);
out.flush();
out.close();
