近距离力量片段变化的软键盘

如何解决近距离力量片段变化的软键盘

最近几天这让我受益匪浅。我有主要活动和两个片段。第一个是屏幕的上半部分，第二个是屏幕的下半部分。第二个片段有 EditText。对焦时，键盘打开。如果用户添加文本，在关闭底部片段变化。它由与顶部片段相同的内容填充。这是不希望的。如果用户不添加文本并且文本框保持为空，则键盘关闭并保留底部片段。所需的行为是无论 EditText 内容如何，底部片段都保持不变。谢谢你的帮助！我认为这是所有相关代码：

AndroidManifest

android:windowSoftInputMode="adjustPan"

主要活动

public class Main extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {

private DrawerLayout drawer;
FragmentChart fragmentChart;
FragmentTable fragmentTable;
FragmentStudy fragmentStudy;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main_activity);

    fragmentChart = new FragmentChart();
    fragmentTable = new FragmentTable();
    fragmentStudy = new FragmentStudy();

    getwindow().setSoftInputMode(WindowManager.LayoutParams.soFT_INPUT_ADJUST_PAN);

    drawer = findViewById(R.id.drawer_layout);
    NavigationView navigationView = findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);

    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this,drawer,toolbar,R.string.navigation_drawer_open,R.string.navigation_drawer_close);
    drawer.addDrawerListener(toggle);
    toggle.syncState();

    if (savedInstanceState == null) {
        getSupportFragmentManager().beginTransaction().replace(R.id.top_fragment_layout,fragmentChart).commit();
        getSupportFragmentManager().beginTransaction().replace(R.id.bottom_fragment_layout,fragmentTable).commit();
        navigationView.setCheckedItem(R.id.practice);
    }
}

@Override
public boolean onNavigationItemSelected(@NonNull @NotNull MenuItem item) {
    if (item.getItemId() == R.id.study) {
        getSupportFragmentManager().beginTransaction()
                .replace(R.id.top_fragment_layout,fragmentChart)
                .replace(R.id.bottom_fragment_layout,fragmentStudy)
                .commit();
    }
    if (item.getItemId() == R.id.practice) {
        getSupportFragmentManager().beginTransaction()
                .replace(R.id.top_fragment_layout,fragmentTable)
                .commit();
    }
    drawer.closeDrawer(GravityCompat.START);
    return true;
}

@Override
public void onBackpressed() {
    if (drawer.isDrawerOpen(GravityCompat.START)) {
        drawer.closeDrawer(GravityCompat.START);
    } else {
        super.onBackpressed();
    }
}
