这是我正在尝试做的。我有 4 张图片，它们在一个 LinearLayout 中，而 LinearLayout 是 RelativeLayout 的子项。我已经成功实现了 onClickListener。也许我的问题有点不同，但一切都是相关的。
我不知道如何将图像扩展到全屏，因为图像在一个 LinearLayout 中，它在那个 RelativeLayout 中，也许当我显示时一切都会清楚你们这些 xml 代码。
我想让 ImageView 在点击时全屏显示，并且在我点击后退按钮时能够返回。为此，我可能需要使用 onBackPressed
图像在底部。
这是xml代码:

这里是 onClickListener:
image1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
int px = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_SP, 115, getResources().getDisplayMetrics());
int px1 = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_SP, 150, getResources().getDisplayMetrics());
LinearLayout.LayoutParams p = new LinearLayout.
LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
p.weight = 1;
if(isImageFitToScreen) {
image1.setMinimumWidth(px);
image1.setMinimumHeight(px1);
image1.setAdjustViewBounds(true);
isImageFitToScreen=false;
}else{
image1.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT));
image1.setScaleType(ImageView.ScaleType.FIT_XY);
isImageFitToScreen=true;
}
}
});
最佳答案
为了提供 Ben 的答案的替代方案并充实我之前的评论，一种可能是在 xml 中创建一个占据整个屏幕的 ImageView，它的可见性设置为 gone。按下按钮时，将图像加载到此 ImageView 中，然后再次按下按钮时将可见性设置为 gone。
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
xmlns:android="http://schemas.android.com/apk/res/android"
>
<ScrollView>
<!-- Everything else! -->
</ScrollView>
<ImageView
android:id="@+id/full_screen_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone" />
</RelativeLayout>
在您的 Activity 的 onCreate() 方法中:
@Override
public void onCreate(Bundle mySavedInstances) {
ImageView fullScreenContainer = (ImageView) findViewById(R.id.full_screen_container);
image1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//However it is you load your images
fullScreenContainer.setImageDrawawble(R.drawable.example);
fullScreenContainer.setVisibility(View.VISIBLE);
}
});
}
@Override
public void onBackPressed() {
if (fullScreenContainer.getVisibility() == View.VISIBLE) {
fullScreenContainer.setImageDrawable(null);
fullScreenContainer.setVisibility(View.GONE);
} else {
super.onBackPressed();
}
}
