Android之截屏代碼

    分享一個簡單的截屏代碼。

1.主Activity

package com.zhf.ScreenshotDemo;import android.app.Activity;import android.graphics.Bitmap;import android.graphics.drawable.BitmapDrawable;import android.os.Bundle;import android.view.Display;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.ImageView;public class ScreenshotDemoActivity extends Activity {private Button shotButton;private ImageView imageView;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);shotButton=(Button)findViewById(R.id.shotButton);imageView=(ImageView)findViewById(R.id.imageView);shotButton.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {//Bitmap-->DrawableBitmapDrawable bd=new BitmapDrawable(shot());imageView.setBackgroundDrawable(bd);//imageView.setImageBitmap(shot());}});}/** * 截屏方法 * @return */private Bitmap shot() {View view = getWindow().getDecorView();Display display = this.getWindowManager().getDefaultDisplay();view.layout(0, 0, display.getWidth(), display.getHeight());view.setDrawingCacheEnabled(true);//允許當前視窗儲存緩衝資訊，這樣getDrawingCache()方法才會返回一個BitmapBitmap bmp = Bitmap.createBitmap(view.getDrawingCache());return bmp;}}

2.布局

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >    <ImageView android:id="@+id/imageView"        android:layout_width="fill_parent"        android:layout_height="350dip"        />    <Button android:id="@+id/shotButton"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="shot"/></LinearLayout>
