如何從圖庫中選擇圖片？

Question

Iam試圖從模擬器中的圖庫中選擇圖片。當我點擊瀏覽日蝕在logcat中顯示W/IInputConnectionWrapper: showStatusIcon on inactive InputConnection，但模擬器帶我到畫廊。當我選擇一張照片時，它沒有被選中。使用下面的代碼：

package com.textapi; 

import android.app.Activity; 
import android.content.Intent; 
import android.database.Cursor; 
import android.net.Uri; 
import android.os.Bundle; 
import android.provider.MediaStore; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.Button; 
import android.widget.Toast; 

public class SendMMSActivity extends Activity { 
    private static final int SELECT_PICTURE = 1; 
    private String selectedPath, extension = ""; 
    Uri selectedVideoUri; 
    Button btnBrowse; 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.send_mms); 
     btnBrowse=(Button)findViewById(R.id.bnBrowse); 
     btnBrowse.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View arg0) { 
       // TODO Auto-generated method stub 
       Intent intent = new Intent(); 
       intent.setType("image/*"); 
       intent.setAction(Intent.ACTION_GET_CONTENT); 
       startActivityForResult(
         Intent.createChooser(intent,"Select Picture"), 
         SELECT_PICTURE); 
      } 
     }); 
    } 

    public void onActivityResult(int requestCode, int resultCode, 
      final Intent data) { 
     if (resultCode == RESULT_OK) { 
      if (requestCode == SELECT_PICTURE) { 
       selectedVideoUri = data.getData(); 
       selectedPath = getPath(selectedVideoUri); 
       System.out.println("Path--->>"+selectedPath); 
       int pos = selectedPath.lastIndexOf("."); 
       if (pos > 0) { 
        extension = selectedPath.substring(pos + 1); 
       } 
      } 
     } 
    } 

    // We can get the path of the video using this method. 
    public String getPath(Uri uri) { 
     String[] projection = { MediaStore.Images.Media.DATA }; 
     Cursor cursor = managedQuery(uri, projection, null, null, null); 
     int column_index = cursor 
       .getColumnIndexOrThrow(MediaStore.Images.Media.DATA); 
     cursor.moveToFirst(); 
     return cursor.getString(column_index); 
    } 


} 

請幫我選擇圖片。而且我還需要使用MVAAYOO api將圖片庫中的圖片發送到手機號碼。如果有人知道，請幫助我。

@Override 
     public void onClick(View arg0) { 
      // TODO Auto-generated method stub 
      Intent i = new Intent(
       Intent.ACTION_PICK, 
       android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
     startActivityForResult(i, RESULT_LOAD_IMAGE); 
     } 
    }); 
} 
    // For Image Loading 
@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 

    if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK 
      && null != data) { 
     Uri selectedImage = data.getData(); 
     String[] filePathColumn = { MediaStore.Images.Media.DATA }; 

     Cursor cursor = getContentResolver().query(selectedImage, 
       filePathColumn, null, null, null); 
     cursor.moveToFirst(); 

     int columnIndex = cursor.getColumnIndex(filePathColumn[0]); 
     picturePath = cursor.getString(columnIndex); 
     cursor.close(); 

     ImageView imageView = (ImageView) findViewById(R.id.imageView1); 
     imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath)); 

    } 

}

btnBrowse.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View arg0) { 
      // TODO Auto-generated method stub 
      getfrmGallery() 
     } 
    }); 


File fp; 
Drawable d; 

public void getfrmGallery() 
{ 
// To open up a gallery browser 
Intent intent = new Intent(); 
intent.setType("image/*"); 
intent.setAction(Intent.ACTION_GET_CONTENT); 
startActivityForResult(Intent.createChooser(intent, "Select Picture"),1); 
// To handle when an image is selected from the browser, add the following to your Activity 
} 
@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) { 
if (resultCode == RESULT_OK) {// if image selected 
if (requestCode == 1) { 
// currImageURI is the global variable I�m using to hold the content:// URI of the image 
Uri currImageURI = data.getData(); 
System.out.println("Hello======="+getRealPathFromURI(currImageURI)); 
String s= getRealPathFromURI(currImageURI);//get the image path 
File file = new File(s); 

if (file.exists()) { // if the file exists in the path 
fp=file.getAbsolutePath(); //get the absolute path of the image 
d = Drawable.createFromPath(file.getAbsolutePath());//create a drawable form the path 
imageView.setBackgroundDrawable(d);//set imageview with the selected image 
} 
else 
{ 
System.out.println("File Not Found"); // image not found 
} 
} 
}

public class MainActivity extends Activity { 
    private static int RESULT_LOAD_IMAGE = 1; 
    Uri myPicture = null; 
    Button buttonLoadImage; 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     //getting View 
     buttonLoadImage = (Button) findViewById(R.id.button2); 

     buttonLoadImage.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View arg0) { 

       Intent i = new Intent(
         Intent.ACTION_PICK, 
         android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 

       startActivityForResult(i, RESULT_LOAD_IMAGE); 
      } 
     }); 
    } 


    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 

     if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) { 
      Uri selectedImage = data.getData(); 
      String[] filePathColumn = { MediaStore.Images.Media.DATA }; 

      Cursor cursor = getContentResolver().query(selectedImage, 
        filePathColumn, null, null, null); 
      cursor.moveToFirst(); 

      int columnIndex = cursor.getColumnIndex(filePathColumn[0]); 
      String picturePath = cursor.getString(columnIndex); 
      cursor.close(); 

      ImageView imageView = (ImageView) findViewById(R.id.imageView1); 
      imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));  
     } 
    } 
}
