我使用 imageview.onclick 来调用厨房并选择图片，第一次单击图像不会出现在 imageview 中，但第二次单击图像会更新，我不知道为什么或有任何想法吗？
imageView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(Intent.createChooser(intent, "Select Picture"), REQUEST_GALLERY);
imageView.setImageBitmap(resize);
}
});
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_GALLERY && resultCode == RESULT_OK) {
Uri uri = data.getData();
try {
bitmap = Media.getBitmap(this.getContentResolver(), uri);
resize = Bitmap.createScaledBitmap(bitmap, newWidth, newHeight, false);
} catch (Exception e) {
e.printStackTrace();
}
}
}
最佳答案
移动imageView.setImageBitmap(resize);到 onActivityResult
imageView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(Intent.createChooser(intent, "Select Picture"), REQUEST_GALLERY);
}
});
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_GALLERY && resultCode == RESULT_OK) {
Uri uri = data.getData();
try {
bitmap = Media.getBitmap(this.getContentResolver(), uri);
resize = Bitmap.createScaledBitmap(bitmap, newWidth, newHeight, false);
imageView.setImageBitmap(resize);
} catch (Exception e) {
e.printStackTrace();
}
}
}
关于java - 我的 ImageView 有一些错误有人知道吗？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/20303975/
