在主界面里面弹一个Dialog
主要内容由dialog来完成
自定义dialog
public class CustomDialog extends AppCompatDialog {
public CustomDialog(Context context) {
super(context,R.style.dialog);
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
supportRequestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.layout_dialog);
int widthPixels = getContext().getResources().getDisplayMetrics().widthPixels;
WindowManager.LayoutParams layoutParams = getWindow().getAttributes();
layoutParams.gravity = Gravity.BOTTOM;
layoutParams.width = widthPixels;
getWindow().setAttributes(layoutParams);
}
}
自定义dialog的主题
<style name="dialog" parent="Theme.AppCompat.Dialog">
<item name="android:windowBackground">@android:color/transparent</item>
</style>
