打開照相機
<1>Intent i = new Intent(Intent.ACTION_CAMERA_BUTTON, null);
this.sendBroadcast(i);
<2>long dateTaken = System.currentTimeMillis();
String name = createName(dateTaken) + ".jpg";
fileName = folder + name;
ContentValues values = new ContentValues();
values.put(Images.Media.TITLE, fileName);
values.put("_data", fileName);
values.put(Images.Media.PICASA_ID, fileName);
values.put(Images.Media.DISPLAY_NAME, fileName);
values.put(Images.Media.DESCRIPTION, fileName);
values.put(Images.ImageColumns.BUCKET_DISPLAY_NAME, fileName);
Uri photoUri = getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent inttPhoto = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
inttPhoto.putExtra(MediaStore.EXTRA_OUTPUT, photoUri);
startActivityForResult(inttPhoto, 10);
從Gallery選取圖像
Intent i = new Intent();
i.setType("image/*");

打開錄音機

顯示應用詳細列表
Uri uri = Uri.parse("market://details?id=app_id");
Intent it = new Intent(Intent.ACTION_VIEW, uri);
startActivity(it);
//where app_id is the application ID, find the ID
/ /by clicking on your application on Market home
//page, and notice the ID from the address bar
剛才找app id未果，結果發現用package name也可以
Uri uri = Uri.parse("market://details?id=");
這個簡單多了
尋找應用
Uri uri = Uri.parse("market://search?q=pname:pkg_name");
Intent it = new Intent(Intent.ACTION_VIEW, uri);
startActivity(it);
//where pkg_name is the full package path for an application

調用android自帶的圖片瀏覽器
方法一
Java code
File file=newFile("/sdcard/IMG/1.jpg");
Intent it=newIntent(Intent.ACTION_VIEW);
Uri mUri=Uri.parse("file://"+file.getPath());
it.setDataAndType(mUri,"image/*");
startActivity(it);
方法二Java code
ComponentName componentName=newComponentName("com.cooliris.media","com.cooliris.media.Gallery"); Intent intent=newIntent();
intent.setComponent(componentName);
File file=newFile("/sdcard/IMG/1.jpg");
Uri mUri=Uri.parse("file://"+file.getPath());
intent.setData(mUri);
intent.setAction(Intent.ACTION_VIEW);
startActivity(intent);
調用android自帶錄音軟件
Intent intent = new Intent("android.provider.MediaStore.RECORD_SOUND");
startActivityForResult(intent, 0);
調用android系統自帶的程序安裝器安裝程序
Intent intent = new Intent(Intent.ACTION_VIEW);intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
//filePath為文件路徑
intent.setDataAndType(Uri.parse("file://"+filePath), "application/vnd.android.packagearchive");
startActivity(intent);
調用android自帶播放器播放音樂
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri, MimeType);
startActivity(intent);
調用android自帶視頻播放
Android中除了利用VideoView播放視頻文件外，還可以用發送Intent來調用視頻播放模塊。方法如下：
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent intent = new Intent(Intent.ACTION_VIEW);
String type = "video/mp4";
Uri name = Uri.parse("file:///sdcard/test.mp4");
intent.setDataAndType(name, type);
intent.setClassName("com.cooliris.media", "com.cooliris.media.MovieView");
startActivity(intent);
}
代碼中的intent.setClassName("com.cooliris.media", "com.cooliris.media.MovieView"); 一句是選擇合適的視頻播放器，如果沒有這一句，當Android中有多個視頻播放器時可能會彈出個選擇框，添加上這一句直接進入選擇的媒體播放器。不同的媒體播放器存放的位置也有所不同，查找播放器位置較為簡單的方法為點擊視頻文件并選取所需的媒體播放器的同時查看Log信息，在Log信息中查看視頻播放器的位置，填上去就可以了。
這種方法對于只要求打開并播放視頻文件的應用是可以的，但如果需要對播放器進行控制還是用VideoView的好些，相對來說VideoView容易控制。
調用android系統自帶瀏覽器
方法1：
Uri?uri?=?Uri.parse("http://blog.csdn.net/u0fly");
Intent?it??=newIntent(Intent.ACTION_VIEW,uri);
startActivity(it);
方法2：
Intent?mIntent?=newIntent();ComponentName?comp?=newComponentName("com.android.browser","com.android.browser.BrowserActivity");mIntent.setComponent(comp);
mIntent.setAction("android.intent.action.MAIN");
startActivity(mIntent);
方法1可以指定打開的頁面。
還有一種方法是在當前程序的窗口中以WebView的形式打開一個網頁
注意：需要在AndroidManifest.xml中添加
main.xml
android:layout_height="fill_parent" android:id="@+id/wv" />
主程序：
final Activity activity = this;
WebView wv=(WebView)this.findViewById(R.id.wv);
wv.getSettings().setJavaScriptEnabled(true);
wv.setWebChromeClient(new WebChromeClient(){
public void onProgressChanged(WebView view, int progress) {
// Activities and WebViews measure progress with different scales.
// The progress meter will automatically disappear when we reach 100%
activity.setProgress(progress * 1000);
}
});
wv.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, "Oh no! " + description, Toast.LENGTH_SHORT).show();
}
});
wv.loadUrl("http://www.google.com");
