我正在开发用于编辑照片的应用程序。
我在第一个活动中有一个按钮,在第二个活动中有ImageView。当我点击按钮它会打开画廊,我将能够选择一个图像。所选图像需要在第二个活动中出现在我的ImageView中,但事实并非如此。暂时我在第一个活动中显示图像,但是任何人都可以建议我如何在下一个活动中显示该图像。
以下是我的代码。
public class Camera_Gallery_Option extends Activity {
private static final int CAMERA_REQUEST = 1888;
private static final int SELECT_PICTURE = 1;
private String selectedImagePath;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.camera_gallery_option);
Button galleryButton= (Button) findViewById(R.id.button1);
galleryButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(
Intent.createChooser(intent, "Select Picture"),
SELECT_PICTURE);
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
imageview.setImageURI(selectedImageUri);
}
}
}
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);
}
答案 0 :(得分:1)
将 selectedImageUri 传递给第二个活动,并在第二个活动中将uri设置为图像视图?
startActivity(new Intent(this, SecondActivity.class).setData(selectedImageUri));
在SecondActivity中:
protected void onCreate(Bundle savedInstanceState) {
...
imageView.setImageURI(getIntent().getData());
}
