我通过使用LayoutInflater在我的MainActivity.java类中使用Imageview 2次。在那个活动中我通过使用滚动来扩充这么多布局每件事情都很好。但是这个imageview不能正常工作。当用户点击imageview时显示弹出窗口。当我第一次显示膨胀时它工作。它不能第二次充气。
在我的主要活动中包含edittext。当用户在edittext中输入High时，我想显示2个imageview时间。如果用户输入Low我想显示单个imageview.One imageview显示屏幕顶部，一个显示屏幕底部。
这是我的代码。
这是我的 imageview.xml：
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/attach_photo_layout"
android:layout_width="match_parent"
android:layout_height="80dp"
android:layout_margin="10dp" >
<TextView
android:id="@+id/attach_photo_titile_textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:padding="5dp"
android:text="@string/attach_photo_to_job"
android:textColor="@android:color/white" />
<ImageView
android:id="@+id/attach_photo_camera_ImageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_toRightOf="@+id/attach_photo_titile_textView"
android:contentDescription="@string/app_name"
android:clickable="true"
android:src="@drawable/image_placeholder" />
</RelativeLayout>
我使用。
在我的 main.xml 中使用此布局我使用LayoutInflater在My MainActivity.java 中调用 imageview.xml 布局。
这是我的代码：
public void getAudioRecordLayout() {
testView = testInflater.inflate(
getResources().getLayout(
R.layout.imageview), null);
mWorkDetailAttachImageView = (ImageView) findViewById(R.id.attach_photo_camera_ImageView);
mIncludeHighLayout = (LinearLayout) findViewById(R.id.include_High);
mIncludeLowLayout = (LinearLayout) findViewById(R.id.include_Low);
mIncludeRecordAudioInWorkDetailLayout.setVisibility(View.VISIBLE);
mIncludeRecordAudioInRecordOfInspectionLayout
.setVisibility(View.GONE);
mWorkDetailAttachImageView.setOnClickListener(this);
}
编辑＃1：
当我第二次显示imageview时，imageview显示在另一个膨胀视图中。
图片视图OnclickListiener：
if (v == mWorkDetailAttachImageView) {
LayoutInflater inflater = LayoutInflater.from(this);
View view = inflater.inflate(R.layout.add_picture_image_dialog,
null);
final AlertDialog alertDialog;
AlertDialog.Builder builder = new AlertDialog.Builder(
TestResultsActivity.this);
builder.setView(view);
builder.setInverseBackgroundForced(true);
builder.setCancelable(true);
alertDialog = builder.create();
alertDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
alertDialog.show();
Button cancel = (Button) view

Button takeNew = (Button) view
.findViewById(R.id.take_new_photo_btn);

// TODO Auto-generated method stub

请任何人帮助我。
答案 0 :(得分：1)
试试这个..
testView = testInflater.inflate(getResources().getLayout(R.layout.imageview), null);
mWorkDetailAttachImageView = (ImageView) testView.findViewById(R.id.attach_photo_camera_ImageView);
添加your click
mWorkDetailAttachImageView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Button cancel = (Button) view
.findViewById(R.id.cancel_img_dialog_btn);
Button takeNew = (Button) view
.findViewById(R.id.take_new_photo_btn);
Button chooseExisting = (Button) view
.findViewById(R.id.choose_from_existing_img_btn);
takeNew.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent cameraIntent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
alertDialog.dismiss();
}
});
chooseExisting.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
alertDialog.dismiss();
}
});
cancel.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
alertDialog.dismiss();
}
});
}
}
});
或者
if (v.getId() == R.id.attach_photo_camera_ImageView) {
LayoutInflater inflater = LayoutInflater.from(this);
View view = inflater.inflate(R.layout.add_picture_image_dialog,
null);
final AlertDialog alertDialog;
AlertDialog.Builder builder = new AlertDialog.Builder(
TestResultsActivity.this);
builder.setView(view);
builder.setInverseBackgroundForced(true);
builder.setCancelable(true);
alertDialog = builder.create();
alertDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
alertDialog.show();
Button cancel = (Button) view
.findViewById(R.id.cancel_img_dialog_btn);
Button takeNew = (Button) view
.findViewById(R.id.take_new_photo_btn);
Button chooseExisting = (Button) view
.findViewById(R.id.choose_from_existing_img_btn);
takeNew.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent cameraIntent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
alertDialog.dismiss();
}
});
chooseExisting.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
alertDialog.dismiss();
}
});
cancel.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
alertDialog.dismiss();
}
});
}
修改
LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
testView = inflater.inflate(R.layout.imageview, null);

答案 1 :(得分：0)
您是否在onClick函数中检查了视图，如下所示..
@Override
public void onClick(View v) {
int id = v.getId();
switch (id) {
case R.id.attach_photo_camera_ImageView:
//your click code
break;
}
或尝试下面代码的代码实例..
mWorkDetailAttachImageView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
});
