如果默认为自动，如何获取AppCompatDelegate当前模式 [英] How to get AppCompatDelegate current mode if default is auto

问题描述

我有这样的活动:

package com.nkdroid.daynighttheme;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.app.AppCompatDelegate;
import android.widget.TextView;

public class ModeActivity extends AppCompatActivity {

    private TextView txtModeType;
    int modeType;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_auto_mode);
        txtModeType = (TextView) findViewById(R.id.txtModeType);
        modeType = AppCompatDelegate.getDefaultNightMode();

        if (modeType == AppCompatDelegate.MODE_NIGHT_AUTO) {
            txtModeType.setText("Default Mode: Auto");
        } else if (modeType == AppCompatDelegate.MODE_NIGHT_YES) {
            txtModeType.setText("Default Mode: Night");
        } else if (modeType == AppCompatDelegate.MODE_NIGHT_NO) {
            txtModeType.setText("Default Mode: Day");
        }
    }
}`

如果默认模式设置为自动，是否可以获取当前激活的模式(白天或晚上)?

Is it possible to get which mode (day or night) is active now if default mode set to AUTO?

推荐答案

您可以使用以下代码获取当前模式，

You can get the current mode using the following code,

int currentNightMode = getResources().getConfiguration().uiMode
        & Configuration.UI_MODE_NIGHT_MASK;
switch (currentNightMode) {
    case Configuration.UI_MODE_NIGHT_NO:
        // Night mode is not active, we're in day time
    case Configuration.UI_MODE_NIGHT_YES:
        // Night mode is active, we're at night!
    case Configuration.UI_MODE_NIGHT_UNDEFINED:
        // We don't know what mode we're in, assume notnight
}
