这是我的更改：
// compileSdkVersion 25
buildToolsVersion "25.0.2"
// compile "com.android.support:appcompat-v7:25.0.1"
//compile 'com.android.support:design:24.0.0'

答案 0 :(得分：0)
//我不知道这是对的。我使用以下代码处理此问题： -
if (getSupportActionBar() != null){
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
}
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
finish();
}
});
在我使用这种方式将按钮图标设置为导航
之前// Drawable up = DrawableCompat.wrap（AppCompatDrawableManager.getDrawable（this，R.drawable.back_arrow_new））; // toolbar.setNavigationIcon（up）;
