我想使用意图分享图片,我使用了来自answer of Dixit patel的代码。
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/png");
File.separator + "icon_ask_fatwa_one.png");
Uri imageUri = Uri.parse("android.resource://"+getPackageName()+"/"+"drawable/icon_ask_fatwa_one");
Log.i("imageUri",""+imageUri);
share.putExtra(Intent.EXTRA_STREAM,imageUri);
startActivity(Intent.createChooser(share, "Share Image"));
}}
尝试在模拟器中运行此代码时出现以下错误:

有人可以使用正确的代码吗? ADDED MANIFEST.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.shareimage"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk

使用此代码(我编辑了您的代码):
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/png");
Uri imageUri = Uri.parse("android.resource://com.example.mm/drawable/ic_launcher");
Log.i("imageUri",""+imageUri);
share.putExtra(Intent.EXTRA_STREAM,imageUri);
startActivity(Intent.createChooser(share, "Share Image"));
}
}
