如何在單擊按鈕時從編輯文本更改焦點？

Question

我想知道如何可以集中精力從Edit_text上Button_click 。

默認focus上Edit_text_1當我點擊Save_Button_1我想刪除focus從Edit_text_1並設置focus上Edit_text_2 ，當我點擊Save_button_2我想刪除focus從Edit_text_2並設置focus上Edit_text_1 。

這是我的代碼-

MainActivty.java

public class MainActivity extends AppCompatActivity {

    EditText et1,et2;
    TextView tv1,tv2;

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

        et1 = (EditText)findViewById(R.id.et1);
        et2 = (EditText)findViewById(R.id.et2);

        tv1 = (TextView) findViewById(R.id.tv1);
        tv2 = (TextView) findViewById(R.id.tv2);

        tv1.setText("edit");
        tv1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                et1.clearFocus();
                et2.setFocusable(true);

//                String str = et1.getText().toString();
//                Toast msg = Toast.makeText(getBaseContext(),str,Toast.LENGTH_LONG);
//                msg.show();
            }
        });
        tv2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                et2.clearFocus();
                et1.setFocusable(true);

//                String str = et2.getText().toString();
//                Toast msg = Toast.makeText(getBaseContext(),str,Toast.LENGTH_LONG);
//                msg.show();

            }
        });
    }

}

誰能幫幫我。謝謝。

Answer 1

嘗試這個，

 YOUR_EDITEXT_NAME.requestFocus();

Answer 2

您可以根據需要使用此行代碼

editText.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);

並明確重點

 editText.clearFocus();

Answer 3

試試這個代碼：

property in your xml file. For example (for edittext1):

  android:nextFocusDown="@+id/edittext2"
