如何设置 ImageView 之间的边距？在我的代码中，我通过使用 for 循环创建了许多 ImageView ，但两个 ImageView 之间没有空间如何设置 teo ImageView 之间的边距？ 我如何以编程方式在两个 ImageView 之间添加空间？？？
ScrollView scroll = new ScrollView(MainActivity1.this);
scroll.setLayoutParams(new
LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
btnLO = new LinearLayout(MainActivity1.this);
LinearLayout.LayoutParams paramsLO = new
LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
// button margins
paramsLO.setMargins(0, 0, 0, 0);
// button height/width *pixels*
paramsLO.height = 75;
paramsLO.width = 75;
btnLO.setOrientation(LinearLayout.VERTICAL);
btnLO.setBackgroundColor(5); // not working correctly
//buttons
for (i =0;i <reqdata.length;i++)
{
LinearLayout li=new LinearLayout(this);
li.setOrientation(LinearLayout.HORIZONTAL);
final Button b1 = new Button(MainActivity1.this);
final ImageView imageView = new ImageView(MainActivity1.this);
li.addView(b1, paramsLO);
li.addView(imageView, paramsLO);
btnLO.addView(li);
b1.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
imgIndex = btnLO.indexOfChild(b1)/2;
Toast.makeText(getBaseContext(),imgIndex,
Toast.LENGTH_SHORT).show();
imageView1 = imageView;
Intent pictureActionIntent = new
Intent(MediaStore.ACTION_IMAGE_CAPTURE);
pictureActionIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new
File(SDCARD_ROOT_PATH + SAVE_PATH_IN_SDCARD,IMAGE_CAPTURE_NAME)));
startActivityForResult(pictureActionIntent,CAMERA_PICTURE);
}
});
}
final Button b2 = new Button(MainActivity1.this);
b2.setText("Submit");
b2.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
for (i =0;i <reqdata.length;i++)
{
dbConnector.saveVisitDetail(blob[i],i,Long.valueOf(reqdata[i].getValue())
.longValue());
}
}
});
btnLO.addView(b2, paramsLO);
btnLO.setGravity(Gravity.LEFT | Gravity.CENTER_HORIZONTAL);
scroll.addView(btnLO);
this.addContentView(scroll, new LayoutParams());
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent
imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
if (imageReturnedIntent.getExtras() != null)
{
// here is the image from camera
yourSelectedImage = (Bitmap)
imageReturnedIntent.getExtras().get("data");
ByteArrayOutputStream outStr = new
ByteArrayOutputStream();
yourSelectedImage.compress(CompressFormat.JPEG, 100, outStr);
blob[imgIndex] = outStr.toByteArray();
yourSelectedImage =
BitmapFactory.decodeByteArray(blob[imgIndex], 0, blob.length);
imageView1.setImageBitmap(yourSelectedImage);
}
}
最佳答案
protected void onActivityResult(int requestCode, int resultCode, Intent ata)
{
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
imageView = (ImageView) findViewById(R.id.imageView1);
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo)
}}}
