出现此问题的原因是在布局文件中使用了androidx.mediarouter.app.MediaRouteButton,并且给该按钮设置了半透明的背景。由于androidx.mediarouter.app.MediaRouteButton是一个自定义的控件,它的布局文件中使用了一些特殊的属性和样式,因此在设置背景时会抛出InflateException异常。
要解决这个问题,可以通过以下两种方法来处理:
方法一:使用android.support.v7.app.MediaRouteButton代替androidx.mediarouter.app.MediaRouteButton
implementation 'com.android.support:mediarouter-v7:版本号'
import android.support.v7.app.MediaRouteButton;
public class MainActivity extends AppCompatActivity {
private MediaRouteButton mMediaRouteButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mMediaRouteButton = findViewById(R.id.media_route_button);
}
}
方法二:自定义MediaRouteButton,并处理背景透明的问题
import android.content.Context;
import android.util.AttributeSet;
import androidx.mediarouter.app.MediaRouteButton;
public class CustomMediaRouteButton extends MediaRouteButton {
public CustomMediaRouteButton(Context context) {
super(context);
}
public CustomMediaRouteButton(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CustomMediaRouteButton(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
@Override
public void setBackgroundDrawable(Drawable background) {
// 处理背景透明的问题
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
super.setBackgroundDrawable(background);
} else {
setBackgroundDrawableCompat(background);
}
}
@SuppressWarnings("deprecation")
private void setBackgroundDrawableCompat(Drawable background) {
setBackgroundDrawable(background);
}
}
import com.example.CustomMediaRouteButton;
public class MainActivity extends AppCompatActivity {
private CustomMediaRouteButton mMediaRouteButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mMediaRouteButton = findViewById(R.id.media_route_button);
}
}
以上是两种解决androidx.mediarouter.app.MediaRouteButton抛出android.view.InflateException异常的方法,根据具体情况选择其中一种方法进行处理。
