如何在android中突出显示线性布局中的选定项
我有一个线性布局,其中有一个imageview和一个textview,当我触摸线性布局时,它应该用不同的颜色突出显示线性布局内的图像和文本。我曾尝试在按下线性布局时使用set background,因为我使用了ontouch listener,它不显示颜色,即使我尝试通过编程更改颜色,但它不起作用 有人能告诉我当触摸线性布局时,如何更改imageview和textview的颜色吗如何在android中突出显示线性布局中的选定项,android,android-layout,background,Android,Android Layout,Background,我有一个线性布局,其中有一个imageview和一个textview,当我触摸线性布局时,它应该用不同的颜色突出显示线性布局内的图像和文本。我曾尝试在按下线性布局时使用set background,因为我使用了ontouch listener,它不显示颜色,即使我尝试通过编程更改颜色,但它不起作用 有人能告诉我当触摸线性布局时,如何更改imageview和textview的颜色吗 Xml: <LinearLayout android:id="@+id/line

您可以使用此代码。这对我来说很好。也许会有帮助
findViewById(R.id.linear_otherexpense).setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
switch (motionEvent.getAction()) {
case MotionEvent.ACTION_DOWN:
// When you Touch Down
// U can change Text and Image As per your Functionality
break;
case MotionEvent.ACTION_UP:
//When you Release the touch
// U can change Text and Image As per your Functionality
break;
}
return true;
}
});
试试这个
linearLayout = (LinearLayout) findViewById(R.id.linear_otherexpense);
imageView=(ImageView)findViewById(R.id.img_otherexpense);
linearLayout.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
linearLayout.setBackgroundColor(getResources().getColor(R.color.colorAccent));
imageView.setBackgroundColor(getResources().getColor(R.color.colorPrimaryDark));
return true;
}
});
findViewById(R.id.linear_otherexpense).setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
switch (motionEvent.getAction()) {
case MotionEvent.ACTION_DOWN:
// When you Touch Down
// U can change Text and Image As per your Functionality
break;
case MotionEvent.ACTION_UP:
//When you Release the touch
// U can change Text and Image As per your Functionality
break;
}
return true;
}
});
linearLayout = (LinearLayout) findViewById(R.id.linear_otherexpense);
imageView=(ImageView)findViewById(R.id.img_otherexpense);
linearLayout.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
linearLayout.setBackgroundColor(getResources().getColor(R.color.colorAccent));
imageView.setBackgroundColor(getResources().getColor(R.color.colorPrimaryDark));
return true;
}
});
