Question

我在我的活动中显示图像，并希望通过意图分享。我收到错误：不支持图像格式，无论它是jpg还是png。

我的代码中可能存在错误：

public class StartActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_second);

Intent myIntent = getIntent();
int image = myIntent.getExtras().getInt("image");

ImageView imagefull = (ImageView)findViewById(R.id.imageView1);
imagefull.setImageResource(image);


Button share = (Button) findViewById (R.id.buttonshare);
share.setOnClickListener(new OnClickListener() 

{
    @Override
    public void onClick(View arg0) {

    Intent share = new Intent(Intent.ACTION_SEND);

    share.setType("image/*");

    Uri uri = Uri.fromFile(new File(getFilesDir(), "facebook.png"));
    share.putExtra(Intent.EXTRA_STREAM, uri);
    startActivity(Intent.createChooser(share, "Share Image!"));

    } });

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

Answer 1

尝试使用share.setType("image/png");表示PNG，share.setType("image/jpg");表示JPEG。

Answer 2

试试这个： -

shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
shareIntent.setType("image/*");

//set your message
shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, msgText); 
String imagePath = Environment.getExternalStorageDirectory() + File.separator + "image_name.jpg";
File imageFileToShare = new File(imagePath);
Uri uri = Uri.fromFile(imageFileToShare);
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
Uri uri = Uri.fromFile(imageFileToShare);
sharingIntent.putExtra(Intent.EXTRA_STREAM, uri);

共享图像意图 - 不支持图像格式
