我想将Twitter整合到我的Android应用中,以便我可以向Twitter发布消息。
这是我的做法
首先,我为Webview创建了一个对话框 Twitter_Dialog.java
public class Twitter_Dialog extends Dialog
{
static final int BLUE = 0xFF6D84B4;
static final float[] DIMENSIONS_DIFF_LANDSCAPE =
{ 20, 60 };
static final float[] DIMENSIONS_DIFF_PORTRAIT =
{ 40, 60 };
static final FrameLayout.LayoutParams FILL = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT);
static final int MARGIN = 4;
static final int PADDING = 2;
static final String DISPLAY_STRING = "touch";
private String mUrl;
private ProgressDialog mSpinner;
private WebView mWebView;
private LinearLayout mContent;
private TextView mTitle;
public Twitter_Dialog(Context context, String url)
{
super(context);
mUrl = url;
}
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
mSpinner = new ProgressDialog(getContext());
mSpinner.requestWindowFeature(Window.FEATURE_NO_TITLE);
mSpinner.setMessage("Loading...");
mContent = new LinearLayout(getContext());
mContent.setOrientation(LinearLayout.VERTICAL);
setUpTitle();
setUpWebView();
Display display = getWindow().getWindowManager().getDefaultDisplay();
final float scale = getContext().getResources().getDisplayMetrics().density;
int orientation = getContext().getResources().getConfiguration().orientation;
float[] dimensions = (orientation == Configuration.ORIENTATION_LANDSCAPE) ? DIMENSIONS_DIFF_LANDSCAPE : DIMENSIONS_DIFF_PORTRAIT;
addContentView(mContent, new LinearLayout.LayoutParams(display.getWidth() - ((int) (dimensions[0] * scale + 0.5f)), display.getHeight() - ((int) (dimensions[1] * scale + 0.5f))));
}
private void setUpTitle()
{
requestWindowFeature(Window.FEATURE_NO_TITLE);
Drawable icon = getContext().getResources().getDrawable(R.drawable.twitter_icon);
mTitle = new TextView(getContext());
mTitle.setText("Website");
mTitle.setTextColor(Color.WHITE);
mTitle.setTypeface(Typeface.DEFAULT_BOLD);
mTitle.setBackgroundColor(BLUE);
mTitle.setPadding(MARGIN + PADDING, MARGIN, MARGIN, MARGIN);
mTitle.setCompoundDrawablePadding(MARGIN + PADDING);
mTitle.setCompoundDrawablesWithIntrinsicBounds(icon, null, null, null);
mContent.addView(mTitle);
}
private void setUpWebView()
{
mWebView = new WebView(getContext());
mWebView.setVerticalScrollBarEnabled(false);
mWebView.setHorizontalScrollBarEnabled(false);
mWebView.setWebViewClient(new Twitter_Dialog.DialogWebViewClient());
mWebView.getSettings().setJavaScriptEnabled(true);
System.out.println(" mURL = "+mUrl);
mWebView.loadUrl(mUrl);
mWebView.setLayoutParams(FILL);
mContent.addView(mWebView);
}
private class DialogWebViewClient extends WebViewClient
{
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.loadUrl(url);
return true;
}
@Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl)
{
super.onReceivedError(view, errorCode, description, failingUrl);
Twitter_Dialog.this.dismiss();
}
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon)
{
super.onPageStarted(view, url, favicon);
mSpinner.show();
}
@Override
public void onPageFinished(WebView view, String url)
{
super.onPageFinished(view, url);
String title = mWebView.getTitle();
if (title != null && title.length() > 0){
mTitle.setText(title);
if(title.equals("Twitter")){
//This will close the Dialog after tweeting
Twitter_Dialog.this.dismiss();
}
}
mSpinner.dismiss();
}
}
}
//然后进入你的Main.java文件
public class Main extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
new Twitter_Dialog(Main.this,"http://twitter.com/?status="+Uri.encode("Twitter Post")).show();
}
}
除了d.的可靠选择外,您还可以:
ACTION_SEND
Intents
与createChooser()
,如果用户已经安装了Twitter应用程序(如Twidroid),他们可以使用它来更新他们的状态。尝试使用这个简单的客户端 TwitterEasyClient
只需在您的清单中添加权限
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
//setup
TwitterDialogFragment twitterDialog = new TwitterDialogFragment.Builder("message","url.com") //
.callbackUrl("http://www.website.com") //
.consumerKey("XXXXXXXXXXXXXXXXXXXXXX") //
.consumerSecret("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX") //
.urlOAuth("oauth_verifier") //
.build();
//show the dialog
twitterDialog.show(getSupportFragmentManager(), TwitterDialogFragment.class.getSimpleName());
对于一些想要使用twitter4j和DialogFragment同时支持屏幕旋转的人,请查看我的gist https://gist.github.com/zeroarst/10071064adcf171277f9
在编程中,始终选择最新的技术,因为使用Twitter4j可以轻松地集成Twitter,而Twitter提供的API也会不时更改。Twiter SDK是一个不错的选择。您可以在此处找到有关Twitter4j的详细信息。
