我想将SwitchCompat的app:theme属性值更改为其他值(@style/switchColorStyleBlue)。我怎样才能以编程方式做到这一点?(app:theme 基本上改变了切换的颜色)
<android.support.v7.widget.SwitchCompat
android:id="@+id/switch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:theme="@style/switchColorStylePink"/>

我试过这段代码,但它没有显示适当的结果:
SwitchCompat switchCompat = new SwitchCompat(this);
switchCompat.setId(i);
switchCompat.setSwitchTextAppearance(getApplicationContext(), R.style.switchColorStylePink);
switchCompat.setChecked(false);
containerRelativeLayout.addView(switchCompat);

我想要的是将主题(开关的颜色)从粉红色更改为蓝色,反之亦然。
试试这个……我已经测试过了,它工作得很好
public class MainActivity extends AppCompatActivity {
int[][] states = new int[][] {
new int[] {-android.R.attr.state_checked},
new int[] {android.R.attr.state_checked},
};
int[] thumbColors = new int[] {
Color.BLACK,
Color.RED,
};
int[] trackColors = new int[] {
Color.GREEN,
Color.BLUE,
};
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SwitchCompat switchCompat = (SwitchCompat) findViewById(R.id.switch);
DrawableCompat.setTintList(DrawableCompat.wrap(switchCompat.getThumbDrawable()), new ColorStateList(states, thumbColors));
DrawableCompat.setTintList(DrawableCompat.wrap(switchCompat.getTrackDrawable()), new ColorStateList(states, trackColors));
}
}

您只需要根据您的要求/需要更新“trackColors”和“thumbColor”。
