我正在创建一个应用程序,允许用户将照片添加到手机库中的imageview,我已经能够成功编码了。我现在希望能够允许用户在照片顶部添加文本,然后将文本和图像作为一个保存回到库中。有没有办法做到这一点?
XML:
<LinearLayout
android:layout_height="match_parent"
android:layout_width="match_parent"
android:orientation="vertical"
xmlns:android="http://schemas.android.com/apk/res/android">
<ImageView android:id="@+id/image" android:layout_height="400dp" android:layout_width="fill_parent"/>
<LinearLayout
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:orientation="horizontal">
<Button
android:id="@+id/chooseimage"
android:layout_height="fill_parent"
android:layout_weight="1"
android:layout_width="fill_parent"
android:text="Choose Image"/>
<Button
android:id="@+id/addtext"
android:layout_height="fill_parent"
android:layout_weight="1"
android:layout_width="fill_parent"
android:text="Add Text"/>
<Button
android:id="@+id/save"
android:layout_height="fill_parent"
android:layout_weight="1"
android:layout_width="fill_parent"
android:text="Save"/>
</LinearLayout>
</LinearLayout>
Member.java
public class MemberActivity extends Activity implements OnClickListener {
/**
* Called when the activity is first created.
*/
private static final int SELECT_IMAGE = 1;
Button openGallery;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.design);
openGallery = (Button) findViewById(R.id.chooseimage);
openGallery.setOnClickListener(this);
}
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.chooseimage:
Intent gallery = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI);
startActivityForResult(gallery, SELECT_IMAGE);
break;
default:
break;
}
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK && requestCode == SELECT_IMAGE) {
Uri selectedImage = data.getData();
String path = getPath(selectedImage);
Bitmap bitmapImage = BitmapFactory.decodeFile(path);
ImageView image = (ImageView) findViewById(R.id.image);
image.setImageBitmap(bitmapImage);
}
}
public String getPath(Uri uri) {
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(uri, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
return cursor.getString(columnIndex);
}
}

是的,有办法做到这一点,
您可以使用buildDrawingCache()
和getDrawingCache()
TextView tv = (TextView)findViewById(R.id.textview);
tv.buildDrawingCache();
ImageView img = (ImageView)findViewById(R.id.imageview);
img.setImageBitmap(tv.getDrawingCache());
您还可以查看this个答案以获取进一步的参考。

Canvas
Bitmap

Bitmap
为图片。答案 2 :(得分:0)
您还可以使用TextView而不是ImageView并将图像设置为TextView.And的背景,之后您还可以向TextView添加文本。 将所有文本保存到某处并再次显示图库再次使用随图像保存的文本。
答案 3 :(得分:0)
TextView tv1 = new TextView(this);
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(80, 100);
tv1.setLayoutParams(layoutParams);
tv1.setText("testing 1 2 3");
tv1.setTextColor(Color.BLACK);
tv1.setBackgroundColor(Color.TRANSPARENT);
在按钮上单击并添加布局 - &gt;您的布局参考,然后
.addview(TV1);
