Android上的按鈕問題

Question

我的佈局很好，只剩下幾個問題：我無法使用mailto和facebook鏈接按鈕。這是我已經試過：

ImageView Button = (ImageView)findViewById(R.id.yourButtonsId); 

Button.setOnClickListener(new OnClickListener() { 
    public void onClick(View v) { 
     Intent intent = new Intent(); 
     intent.setAction(Intent.ACTION_VIEW); 
     intent.addCategory(Intent.CATEGORY_BROWSABLE); 
     intent.setData(Uri.parse("http://www.yourURL.com")); 
     startActivity(intent); 
    } 
}); 

和

TextView textView = (TextView)findViewById(R.id.yourID); 

textView.setOnClickListener(new OnClickListener() { 
    public void onClick(View v) { 
     Intent intent = new Intent(); 
     intent.setAction(Intent.ACTION_VIEW); 
     intent.addCategory(Intent.CATEGORY_BROWSABLE); 
     intent.setData(Uri.parse("http://www.typeyourURL.com")); 
     startActivity(intent); 
    } }); 

Answer 1

如果你想使用的mailto不是把一個EditText在XML和郵件的按鈕。 用戶將在edittext中添加他的電子郵件ID，然後按按鈕發送郵件。當發送按鈕被點擊時，你可以寫如

Button.setOnClickListener(new OnClickListener() { 
public void onClick(View v) { 

Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts(
    "mailto",yourEditTextObj.getText(), null)); 
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Subject"); 
emailIntent.putExtra(Intent.EXTRA_TEXT, "Body"); 
startActivity(Intent.createChooser(emailIntent, "Send email...")); 
} 
}); 

Answer 2

Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts(
     "mailto","abc@gmail.com", null)); 
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Subject"); 
emailIntent.putExtra(Intent.EXTRA_TEXT, "Body"); 
startActivity(Intent.createChooser(emailIntent, "Send email..."));
